The Spinning Leaves Illusion is an example of peripheral drift.
Peripheral drift refers to a visual phenomenon in which stationary patterns or objects at the periphery of our visual field appear to be in motion or exhibit drifting motion. This illusion occurs when specific visual stimuli or patterns are presented in the outer edges of our visual perception.
The peripheral drift illusions like the Spinning Leaves Illusion typically involve the use of repetitive geometric patterns, such as concentric circles, radial lines, spirals, or checkerboard-like patterns. When fixating on the central point of the pattern and maintaining focus, the edges or boundaries of the pattern may appear to be in constant motion, as if they are expanding, contracting, or drifting.
The motion perceived in the peripheral drift illusion is an apparent motion created by the interaction of the visual stimuli with our visual system. The exact mechanisms behind this illusion are not fully understood, but several factors likely contribute to its occurrence. These factors may include the spatial arrangement of the patterns, the specific characteristics of the stimuli, the organization of receptive fields in the visual cortex, and the processing of motion information in our visual system.
The peripheral drift illusion demonstrates the remarkable ability of our visual system to interpret and process visual information, even in the absence of actual physical motion. It highlights the dynamic nature of visual perception and how our brain can generate illusory motion based on the arrangement and characteristics of visual stimuli.
How Does the Spinning Leaves Illusion Work?
The Spinning Leaves Illusion is an example of peripheral drift.
The exact mechanisms underlying the peripheral drift illusion like the Spinning Leaves Illusion are not fully understood. However, several theories attempt to explain how this illusion works. Here are a few possible explanations:
Neural Processing: The peripheral drift illusion may arise from the complex processing of visual information in our visual system. When we fixate on a central point, the motion-sensitive neurons in our visual cortex respond to the visual stimuli at the periphery of our visual field. These neurons analyze the motion information and send signals to the brain, which are interpreted as motion perception.
Lateral Inhibition: Lateral inhibition is a fundamental process in our visual system that enhances the detection of edges and boundaries. It involves the suppression of activity in neighboring neurons when a specific neuron is active. In the case of the peripheral drift illusion, the high-contrast repetitive patterns at the periphery of our vision can activate neurons that signal motion, while the surrounding neurons are inhibited. This interaction between active and inhibited neurons may create the illusion of motion along the edges of the pattern.
Eye Movements: Eye movements, such as microsaccades, are small involuntary eye movements that occur even when we try to fixate on a specific point. These eye movements can introduce subtle changes to the retinal image, which may be interpreted by the visual system as motion. The presence of repetitive patterns at the periphery of our visual field can amplify these perceived motions.
Adaptation and Contrast: Prolonged exposure to a specific visual stimulus can lead to adaptation, where neurons in the visual system become less responsive to that stimulus. When the stimulus is removed or altered slightly, the non-adapted neurons can respond more strongly, creating the perception of motion. This adaptation and contrast interaction may contribute to the illusion of motion in the peripheral drift illusion.
These explanations are theoretical and not exhaustive. The peripheral drift illusion like the Spinning Leaves Illusion is still an area of ongoing research, and further studies are needed to fully understand the underlying mechanisms. Nonetheless, these theories provide insights into how our visual system processes and interprets visual information, resulting in the perception of motion even in the absence of actual physical movement.
Some Similar Illusions
The Spinning Leaves Illusion is an example of peripheral drift.
There are several illusions that share similarities with the Spinning Leaves Illusion in terms of their effects on visual perception. Here are a few examples of similar illusions to the Spinning Leaves Illusion:
Motion Binding Illusion: Motion binding illusions involve the perception of motion in one object due to the motion of another object, even though there is no direct physical connection between them. This illusion shares similarities with peripheral drift in terms of creating the perception of motion based on spatial relationships and visual interactions.
Pinna-Brelstaff Illusion: The Pinna-Brelstaff illusion involves a pattern of concentric circles or spirals that, when rotated, appears to move in the opposite direction. This illusion creates a sense of motion that contradicts the actual physical rotation, similar to how peripheral drift creates illusory motion at the edges of a stationary pattern.
Rotating Snakes Illusion: The rotating snakes illusion features a pattern of interconnected circles that appear to rotate or undulate, even though the pattern itself is static. This illusion shares similarities with peripheral drift in terms of creating the perception of motion or rhythmic changes in a stationary pattern.
Fraser Spiral Illusion: The Fraser spiral illusion consists of concentric circles arranged in a spiral pattern. Despite being composed of static circles, the arrangement creates the illusion of a continuously expanding spiral. This illusion is akin to peripheral drift in terms of creating a sense of motion or expansion in a stationary image.
Enigma Illusion: The enigma illusion involves a repeating pattern of squares or rectangles with alternating orientations. When fixating on the central point of the pattern, the squares may appear to shift or move in a pulsating manner, similar to the perceived motion in peripheral drift.
These illusions, like the Spinning Leaves Illusion, exploit various visual cues, such as spatial arrangements, contrast, and repetitive patterns, to trick our visual system into perceiving motion or dynamic changes in static stimuli. They demonstrate the remarkable capabilities of our visual system to interpret and process visual information, leading to perceptual experiences that deviate from physical reality.

The Moving Circles Illusion is an example of illusory motion.
In this type of illusion, static shapes or patterns appear to move or exhibit motion, even though there is no actual physical movement occurring.
There are various types of illusory motion like the Moving Circles Illusion, and here are a few examples:
Op Art: Op Art, short for optical art, is an artistic style that utilizes geometric shapes, patterns, and contrasting colors to create the illusion of movement or vibration. Artists employ various techniques, such as the repetition of shapes, gradients, and perspective distortion, to evoke a sense of motion in static images.
Motion Grid Illusion: The motion grid illusion involves a grid of intersecting lines with small dots at the intersections. When fixating on a specific point, the dots appear to move or “pop” in and out of visibility due to the interaction between neighboring lines.
Akiyoshi’s Illusion: Akiyoshi Kitaoka, a renowned visual illusion artist, has created several illusions that give the impression of movement in static images. For example, his “Rotating Snakes” illusion features a pattern of interconnected circles that appear to rotate despite being stationary.
Fraser Spiral Illusion: The Fraser spiral illusion is characterized by a spiral pattern composed of concentric circles. Although the circles are arranged in a static manner, they give the perception of a spiraling motion due to the arrangement of the black and white sectors within each circle.
Kitaoka’s Rotating Circles: Another illusion created by Akiyoshi Kitaoka involves concentric circles with alternating color patterns. When observed, the circles can give the impression of rotation or movement.
These illusions exploit various visual cues, such as contrast, color, and spatial relationships, to trick our visual system into perceiving motion. They demonstrate the remarkable ability of our brain to interpret static visual information in ways that deviate from physical reality, resulting in the illusion of movement.
How Does Moving Circles Illusion Work?
The Moving Circles Illusion is an example of illusory motion.
The illusory motion or motion illusions like the Moving Circles Illusion works by exploiting specific mechanisms and processes in our visual system. While the exact mechanisms behind each illusion may vary, here are some general explanations for how illusory motion works:
Neural Adaptation: Prolonged exposure to a particular visual stimulus can lead to neural adaptation, where the neurons responsible for processing that stimulus become less responsive over time. When the stimulus is removed or altered slightly, the less adapted neurons respond more strongly, creating the perception of motion.
Contrast and Lateral Inhibition: Illusory motion often involves high contrast or conflicting visual elements. Our visual system relies on contrast to detect edges and boundaries between objects. When contrasting elements are arranged in a specific pattern or configuration, they can create an illusion of motion through lateral inhibition, where neighboring neurons suppress each other’s activity.
Eye Movements and Fixation: Eye movements and fixation play a role in illusory motion. Small involuntary eye movements called microsaccades continuously occur even when we attempt to fixate on a specific point. These eye movements can introduce subtle changes in the retinal image, which can be interpreted as motion by our visual system.
Gestalt Principles: Illusory motion can also be attributed to the Gestalt principles of visual perception, particularly the principle of “common fate.” According to this principle, objects that move together or share a common direction tend to be perceived as part of the same entity in motion. Illusions that utilize repetitive patterns or shapes can exploit this principle, leading to the perception of motion.
Brain Interpretation: Our brain is actively involved in interpreting and constructing our visual experiences. It integrates various visual cues, past experiences, and expectations to make sense of the sensory input. In the case of illusory motion, our brain may fill in missing information or extrapolate motion based on incomplete or ambiguous visual cues.
These explanations are general and may not apply to every specific illusion. The exact mechanisms and neural processes underlying each illusion can vary, and ongoing research continues to uncover more insights into the complexities of illusory motion.

There are several illusions that share similarities with the Moving Circles Illusion in terms of their effects on visual perception. Here are a few examples of similar illusions:
Kinetic Illusions: Kinetic illusions involve the perception of movement or motion in static images or patterns. Examples include the “Rotating Rings” illusion, where stationary rings appear to rotate, and the “Leaning Tower Illusion,” where a tilted tower appears to lean further than it actually does.
Anomalous Motion Illusions: Anomalous motion illusions create the perception of motion that deviates from what is physically present. Examples include the “Rotating Snakes” illusion, where stationary circles appear to rotate, and the “Motion Binding” illusion, where the motion of one object influences the perception of motion in another object.
Illusory Depth Perception: Illusions related to depth perception can create the illusion of movement. For instance, the “Ponzo Illusion” involves two parallel lines converging towards a vanishing point, making one line appear longer and suggesting motion in the scene.
Stroboscopic Motion: Stroboscopic motion illusions involve the perception of continuous motion or animation from a series of static images presented in rapid succession. This effect is utilized in animation and movies to create the illusion of smooth motion.
Tilt Illusions: Tilt illusions involve the perception of tilting or slanting in stationary objects. The “Ebbinghaus Illusion” and the “Poggendorff Illusion” are examples of tilt illusions that can create the impression of objects shifting or tilting in space.
These illusions, like the Moving Circles Illusion, demonstrate the remarkable capabilities and complexities of our visual system. They exploit various visual cues, perceptual mechanisms, and the integration of spatial and temporal information to create perceptual experiences that deviate from physical reality.

Check out this Moving Blue and Yellow Illusion. In the Moving Blue and Yellow Illusion, the image is completely static by the circles appear to move and spiral.
If you are interested in learning more about the Moving Blue and Yellow Illusion, scroll down to read about it!
The Moving Blue and Yellow Illusion is a good example of illusory motion.
Illusory motion refers to the perception of motion or movement in a static image or pattern when, in reality, there is no physical movement occurring. It is an optical illusion that tricks our visual system into perceiving motion where there is none.
Illusory motion can occur due to various factors, including the arrangement of patterns, contrast, and the way our brain processes visual information. Here are a few examples of illusory motion in addition to the Moving Blue and Yellow Illusion:
Rotating Snakes Illusion: In the Rotating Snakes Illusion, static patterns of interlocking rings or spirals appear to rotate or create the perception of motion. Despite the absence of actual movement, our visual system processes the patterns in a way that generates the illusion of rotation.
Motion Aftereffect: The Motion Aftereffect, also known as the waterfall illusion, occurs when we perceive motion in the opposite direction after prolonged exposure to a moving stimulus. For instance, after staring at a downward-flowing waterfall for a while, a stationary scene might appear to move upward.
Peripheral Drift Illusion: The Peripheral Drift Illusion involves a pattern of radial lines or concentric circles that appear to move or rotate subtly when viewed peripherally. The perceived motion is a result of the interaction between eye movements and the arrangement of the pattern.
Spinning Dancer Illusion: The Spinning Dancer Illusion features an image of a silhouette of a spinning dancer. Due to the lack of visual cues, the direction of the dancer’s spin can appear to change spontaneously, creating the illusion of movement.
These illusions like the Moving Blue and Yellow Illusion demonstrate how our visual system can perceive motion or movement that is not actually present. They challenge our perception and reveal the complex processes involved in how our brain interprets and processes visual stimuli. Illusory motion illusions highlight the intricate relationship between our eyes, brain, and the processing of visual information.
How Does the Moving Blue and Yellow Illusion Work?
The Moving Blue and Yellow Illusion is a good example of illusory motion.
Illusory motion works by exploiting the way our visual system processes and interprets visual stimuli. Although the visual input may be static, the brain perceives motion based on specific cues and interactions within the visual scene. Here’s a simplified explanation of how illusory motion works including in the the Moving Blue and Yellow Illusion:
Visual Processing: When we view a static image or pattern, our eyes capture the visual information, and it is transmitted to the visual cortex in the brain for processing.
Motion Processing Pathways: Within the visual cortex, there are specialized pathways dedicated to processing motion information. These pathways analyze visual cues related to motion, such as the orientation, arrangement, and contrast of elements in the scene.
Motion Detection: Motion detectors, or neurons specialized in detecting motion, respond to specific characteristics of the visual input, such as changes in position or orientation over time.
Neural Interactions: In illusory motion, specific visual patterns or arrangements interact with the motion detection mechanisms in our visual system. These patterns can create conflicting motion signals or stimulate specific motion-sensitive neurons.
Perceptual Interpretation: The brain interprets the combined input from motion detectors and other visual cues to generate our perception of motion. Illusory motion occurs when the brain misinterprets the static visual input and creates the perception of motion based on the cues it receives.
Context and Expectations: Our perception is also influenced by contextual information and our previous experiences. These factors can further enhance or influence the illusory motion effect.
The specific mechanisms underlying each illusory motion phenomenon can vary, and researchers are still studying the exact processes involved. However, the common thread is that the visual cues and interactions within the visual system lead to the perception of motion where there is none.
Illusory motion like shown in the Moving Blue and Yellow Illusion exploits the complexities of our visual processing system, including motion detection, neural interactions, and perceptual interpretation, to create the compelling illusion of movement in static images or patterns.
Some Similar Illusions
The Moving Blue and Yellow Illusion is a good example of illusory motion.
There are several illusions that involve the perception of illusory motion in addition to the Moving Blue and Yellow Illusion. Here are a few examples:
Rotating Snakes Illusion: In the Rotating Snakes Illusion, static patterns of interlocking rings or spirals appear to rotate or create the perception of motion. The illusory motion is generated by the arrangement of the patterns and the interaction of the visual system’s motion-sensitive neurons.
Motion Quartet: The Motion Quartet illusion consists of four identical shapes positioned in a square. When viewed, the shapes appear to move in a rotating pattern, even though they are static. This illusion is a result of the conflicting motion signals generated by the spatial arrangement of the shapes.
Enigma Illusion: The Enigma illusion involves a grid of squares with alternating dark and light bars. When observed, the dark bars appear to move along the grid in waves, creating the perception of illusory motion propagating across the grid.
Pinna-Brelstaff Illusion: In the Pinna-Brelstaff illusion, a pattern of alternating radial black and white lines is placed over a rotating disk. When fixating on the center of the disk and staring at the pattern, the lines appear to rotate in the opposite direction of the disk’s motion.
Fraser Spiral Illusion: The Fraser Spiral is an illusion where a spiral pattern appears to rotate outward continuously, even though it is composed of a series of concentric circles. The perception of rotation arises from the way our visual system processes the overlapping patterns.
Peripheral Drift Illusion: The Peripheral Drift illusion involves a pattern of radial lines or concentric circles that appear to subtly move or rotate when viewed peripherally. The illusory motion is a result of the interaction between eye movements and the arrangement of the pattern.
These illusions like the Moving Blue and Yellow Illusion demonstrate how our visual system can perceive illusory motion or movement in static images or patterns. They exploit our brain’s processing of visual cues, motion detection mechanisms, and contextual information to create compelling and often surprising perceptual experiences.

The Moving Colorful Circles Illusion is an example of anomalous motion.
Anomalous motion refers to a visual illusion in which a stationary image appears to move or create an illusion of motion. It involves the perception of motion where there is none or a discrepancy between the actual motion and the perceived motion.
Anomalous motion like shown in the Moving Colorful Circles Illusion can occur due to various factors, including conflicting visual cues, spatial interactions, and our brain’s interpretation of the visual input. Here are a few examples of anomalous motion illusions:
Rotating Snakes Illusion: The Rotating Snakes Illusion is an example of anomalous motion where static images of interlocking rings appear to rotate or move. The perceived motion is an illusion created by the arrangement of the patterns and the interaction of the visual system’s motion-sensitive neurons.
Wagon-Wheel Effect: The Wagon-Wheel Effect occurs when a wheel or rotating object appears to rotate in the opposite direction or at a different speed than it actually is. This effect can be seen in videos or when observing spinning wheels in film or real life.
Motion Aftereffect: The Motion Aftereffect, also known as the waterfall illusion, happens when an individual perceives motion in the opposite direction after prolonged exposure to a moving stimulus. For instance, after staring at a downward-flowing waterfall, a stationary scene might appear to move upward.
Enigma Illusion: The Enigma Illusion involves a grid of squares with alternating dark and light bars. When the grid is stationary, it can create the perception of waves of motion propagating across the grid.
These examples, along with the Moving Colorful Circles Illusion, demonstrate how our visual system can perceive motion that does not correspond to the actual physical motion or lack thereof. Anomalous motion illusions challenge our understanding of how the brain processes visual information and reveal the complex nature of our visual perception.
How Does the Moving Colorful Circles Illusion Work?
The Moving Colorful Circles Illusion is an example of anomalous motion.
Anomalous motion illusions like the Moving Colorful Circles Illusion work by exploiting the processes involved in visual perception, including motion detection and integration of visual cues. Here’s a simplified explanation of how they work:
Motion Detectors: Our visual system contains neurons called motion detectors that are sensitive to changes in visual stimuli over time. These neurons respond to motion in a particular direction and speed.
Motion Integration: The brain integrates information from different motion detectors to determine the perceived motion of an object or scene. This integration helps create a coherent and stable perception of the visual world.
Conflicting Visual Cues: Anomalous motion illusions arise when there are conflicting visual cues that the brain must interpret. These cues can include patterns, colors, contours, or spatial relationships in the visual stimulus.
Neural Adaptation: Prolonged exposure to a particular motion can lead to neural adaptation, where the neurons involved in perceiving that motion become less responsive. This adaptation can create an imbalance in the activity of motion detectors, influencing the perception of subsequent visual stimuli.
Perceptual Biases: The brain’s interpretation of visual input is influenced by biases and expectations based on prior experiences and learned associations. These biases can affect how we perceive motion and contribute to anomalous motion illusions.
Some Similar Illusions
The Moving Colorful Circles Illusion is an example of anomalous motion.
There are numerous related illusions that play with our perception and challenge our understanding of visual processing. Here are a few notable examples in addition to the Moving Colorful Circles Illusion:
Illusory Motion: Illusory motion illusions create the perception of motion where there is none. The most famous example is the motion of a spinning disk that appears to change direction or speed due to the arrangement of patterns, such as the rotating snakes illusion or the spinning dancer illusion.
Size Illusions: Size illusions distort our perception of the size of objects. Examples include the Ebbinghaus illusion, where a central circle appears larger or smaller depending on the size of surrounding circles, and the Ponzo illusion, where two identical lines appear to be different lengths due to the presence of converging lines.
Ames Room Illusion: The Ames room is a distorted room that creates an illusion of size and shape. When viewed from a specific angle, people standing in the room appear to dramatically change in size, with one person seeming much larger or smaller than the other.
Müller-Lyer Illusion: The Müller-Lyer illusion involves two lines of the same length, one with inward-pointing arrowheads and the other with outward-pointing arrowheads. The line with outward arrowheads appears longer, even though they are the same length.
Kanizsa Triangle: The Kanizsa triangle is an illusion where three illusory triangles are perceived even though the actual lines forming the triangles are incomplete or nonexistent. This illusion demonstrates how our brain fills in missing information based on surrounding context.
Necker Cube: The Necker cube is a classic ambiguous figure that can be perceived as a three-dimensional cube that alternates in orientation. It demonstrates the brain’s tendency to interpret ambiguous stimuli by switching between possible interpretations.
Motion Binding: Motion binding illusions involve perceiving motion where individual elements are stationary. Examples include the apparent motion of stationary dots in the kinetic depth effect and the motion of static images in the motion-induced blindness illusion.
These illusions like the Moving Colorful Circles Illusion highlight the complexity of our visual perception and how our brains interpret visual information. They showcase the influence of context, contrast, motion, and other factors on our visual experiences, often leading to surprising and intriguing perceptual phenomena.

Check out this Expanding Black Illusion. If you stare at the black shape in the middle, it will appear to expand and grow! This Expanding Black Illusion works because of a phenomenon known as lateral inhibition.
If you are interested in learning more about the Expanding Black Illusion, scroll down to read about it!
The Expanding Black Illusion works because of a phenomenon known as lateral inhibition.
Lateral inhibition is a neural mechanism that occurs in the sensory systems of many organisms, including humans. It refers to the process by which neighboring sensory cells or neurons inhibit each other’s activity to enhance contrast and sharpen the perception of sensory information.
In the context of vision, lateral inhibition occurs in the retina, specifically in the network of interconnected cells known as the retina’s horizontal cells and amacrine cells. These cells play a role in processing visual information before it is transmitted to the brain.
When light enters the retina, it stimulates photoreceptor cells called rods and cones. The activated photoreceptors transmit signals to neighboring cells, including bipolar cells, which then transmit the signals to ganglion cells that form the optic nerve. However, lateral inhibition occurs before this transmission.
Horizontal cells in the retina receive input from multiple photoreceptors, while amacrine cells receive input from bipolar cells. Through lateral inhibition, these horizontal and amacrine cells inhibit the activity of neighboring cells, specifically those receiving weaker or less intense signals.
This lateral inhibition mechanism enhances the perception of contrast by suppressing the activity of cells that receive less intense stimulation while allowing cells that receive stronger stimulation to transmit their signals more effectively. This leads to an increased difference in activity levels between neighboring cells, enhancing the perception of edges and boundaries in the visual scene.
Lateral inhibition plays a crucial role in visual processing and is one of the mechanisms that contribute to our ability to perceive and distinguish fine details and contrasts in the visual world and is why the Expanding Black illusion works.
How Does the Expanding Black Illusion Work?
The Expanding Black Illusion works because of a phenomenon known as lateral inhibition.
Lateral inhibition works through a series of interactions between interconnected cells in the sensory system. Here’s a simplified explanation of how it works in the context of vision and examples like the Expanding Black Illusion:
Photoreceptor Stimulation: When light enters the eye, it stimulates the photoreceptor cells in the retina—specifically, the rods and cones.
Signal Transmission: Activated photoreceptor cells transmit signals to neighboring bipolar cells. Bipolar cells serve as an intermediary between the photoreceptors and ganglion cells, which send signals to the brain.
Horizontal Cell Interaction: Horizontal cells in the retina receive input from multiple neighboring photoreceptor cells. These horizontal cells perform lateral inhibition by inhibiting the activity of neighboring cells.
Inhibition of Weaker Signals: Horizontal cells inhibit the activity of neighboring cells that receive weaker or less intense signals. This inhibition reduces the activity of those cells, making their signal less prominent.
Enhancement of Stronger Signals: At the same time, the inhibition of weaker signals allows cells that receive stronger stimulation to transmit their signals more effectively. This enhancement increases the contrast between neighboring cells with stronger signals.
Output to Ganglion Cells: The bipolar cells, which have received inputs from photoreceptors and lateral inhibition from horizontal cells, transmit their modified signals to the ganglion cells.
Perception of Contrast: The enhanced contrast between neighboring cells is transmitted to the brain via the ganglion cells, contributing to the perception of edges, boundaries, and fine details in the visual scene.
By suppressing the activity of neighboring cells with weaker signals and enhancing the activity of cells with stronger signals, lateral inhibition enhances the perception of contrast and sharpens the representation of visual information. It helps our visual system better distinguish between light and dark areas, enhancing our ability to perceive edges, textures, and fine details in the visual world.
Some Similar Illusions
The Expanding Black Illusion works because of a phenomenon known as lateral inhibition.
Lateral inhibition plays a role in various visual illusions like the the Expanding Black Illusion that exploit the contrast enhancement and edge detection mechanisms in our visual system. Here are a few examples of illusions related to lateral inhibition like the Expanding Black Illusion:
Mach Bands: Mach bands are an optical illusion characterized by the perception of light and dark bands at the boundaries between adjacent regions of different intensities. These bands are more pronounced than the actual contrast difference, resulting from lateral inhibition enhancing the perception of contrast.
Hermann Grid Illusion: In the Hermann grid illusion, gray dots appear at the intersections of a black grid on a white background. However, when fixating on a specific intersection, the dot seems to disappear due to lateral inhibition and the way our visual system processes the surrounding visual information.
Simultaneous Contrast Illusion: Simultaneous contrast illusions occur when the perceived brightness or color of an object is influenced by the surrounding context. For example, placing a gray patch on a dark background makes it appear lighter, while the same gray patch on a light background appears darker. This illusion is a result of lateral inhibition amplifying the contrast between the object and its background.
Craik-O’Brien-Cornsweet Illusion: In this illusion, a gradient of color or brightness appears to change abruptly at a boundary where there is no physical change. The perception of the boundary is enhanced due to lateral inhibition, creating a strong contrast where none actually exists.
Mach Dichromacy Illusion: In this illusion, a figure composed of two colors appears to be monochromatic when viewed through a small aperture. Lateral inhibition and the selective processing of color information contribute to this illusion, as the brain selectively interprets the inputs from different regions.
These illusions demonstrate how lateral inhibition affects our perception of contrast, brightness, color, and boundaries in visual stimuli. By exploiting these mechanisms, these illusions challenge our perception and highlight the complex processes involved in visual processing.

In Sumatra, orangutans are found in the northern part of the island, primarily in the Indonesian provinces of North Sumatra and Aceh. These regions consist of dense tropical rainforests, which are the natural habitat of orangutans.
These great apes are well adapted to life in the rainforest canopy, where they spend most of their time. The dense forests provide them with the necessary food sources, shelter, and resources for survival. However, the habitats of orangutans are under threat due to deforestation, illegal hunting, and the expansion of palm oil plantations, which puts their populations at risk.
Efforts are being made by conservation organizations and local governments to protect and preserve the remaining orangutan habitats, ensuring the survival of these incredible creatures in their natural environments.
Fun Facts About Orangutans – What Orangutans Eat
Orangutans have a primarily herbivorous diet, which means they mainly eat plants. In addition to the fun facts about Orangutans, here’s what orangutans eat:
Fruits: Orangutans are frugivores, and a significant portion of their diet consists of various fruits. They consume a wide range of fruits, including figs, durian, lychee, mangos, and jackfruits, among others.
Leaves: Orangutans also consume leaves as a part of their diet. They eat young leaves, shoots, and tender foliage from a variety of trees and plants.
Bark: In addition to fruits and leaves, orangutans sometimes feed on the inner bark of trees. They strip the bark off tree trunks and consume the soft inner layers.
Flowers: Orangutans have been observed eating flowers from certain tree species. They often consume nectar and other parts of the flowers.
Seeds: While feeding on fruits, orangutans also ingest seeds. They may chew on the seeds while eating the fruit pulp, and later, when they defecate, the seeds are dispersed in different areas, contributing to seed dispersal and forest regeneration.
Insects: Although not a major part of their diet, orangutans occasionally eat insects. They may pick insects off leaves or branches and consume them for added protein.
The availability of food sources can vary depending on the season and location. Orangutans have specialized adaptations to their diet, such as strong jaws and teeth for chewing tough foods, and their digestive system is adapted to process the plant material they consume.
Another fun fact about Orangutans is that they are known to have a selective diet, showing preferences for certain fruits or parts of plants. Their food choices also depend on local availability and nutritional needs.
Fun Facts About Orangutans – How Orangutans Behave
Orangutans engage in various activities and behaviors as part of their daily lives. In addition to the fun facts about Orangutans, here are some of the things orangutans do:
Feeding: Orangutans spend a significant amount of time foraging and feeding on fruits, leaves, bark, and other plant materials. They use their long arms and dexterous hands to pluck fruits or leaves from trees and bring them to their mouths.
Nest Building: Orangutans construct nests to sleep and rest in. They gather branches, leaves, and foliage to create a comfortable platform high up in the trees. Each night, they build a new nest for themselves.
Socializing: While orangutans are generally solitary animals, they do engage in social interactions, especially during mating or when mothers are caring for their offspring. Young orangutans may play together, swinging and wrestling with each other.
Tool Use: Orangutans have been observed using tools to aid in their foraging. They might use sticks to extract insects from tree crevices or to access honey. They also use leaves as makeshift umbrellas or as padding to sit on.
Vocalizations: Orangutans communicate through various vocalizations. They make long calls, which are deep, resonant sounds that can carry over long distances in the forest. These calls serve to communicate their presence and maintain territory boundaries.
Traveling: Orangutans move through the forest canopy by swinging from tree to tree, using their long arms and strong grip. They are skilled climbers and can cover large distances in their search for food and suitable habitats.
Exploration: Orangutans are curious animals and often explore their surroundings. They may investigate new food sources, test different tree branches, or explore neighboring areas within their home range.
Resting: Orangutans spend time resting and relaxing between feeding bouts or during the hottest parts of the day. They often rest in their nests or find comfortable spots on tree branches.
Self-grooming: Orangutans engage in self-grooming activities, such as picking through their fur, removing debris, and ensuring cleanliness. Grooming helps them maintain healthy fur and social bonds.
Learning: Young orangutans learn important skills and behaviors from their mothers. They observe and imitate their mothers’ actions, gradually acquiring the knowledge needed for survival in their environment.
Orangutans exhibit a range of behaviors and activities as they navigate their forest habitats, adapt to their surroundings, and interact with other members of their species.
Fun Facts About Orangutans – Anatomy of Orangutans
Orangutans have a unique and distinct anatomy that is well adapted to their arboreal (tree-dwelling) lifestyle. In addition to the fun facts about Orangutans, here are some key features of orangutan anatomy:
Size and Build: Orangutans are the largest arboreal mammals. Adult males can weigh up to 200 pounds (90 kilograms) and reach a standing height of about 4 to 5 feet (1.2 to 1.5 meters). They have a robust, muscular build, while females are smaller and lighter.
Arms and Hands: Orangutans have exceptionally long arms, which are longer than their bodies. Their arms are well-suited for brachiation (swinging from branch to branch) and reaching out to grasp tree branches. They have four long fingers and an opposable thumb on each hand, enabling them to grip and manipulate objects with precision.
Leg Structure: While orangutans primarily move through trees, they also walk on all fours on the ground. Their legs are relatively shorter compared to their arms but are still strong and sturdy. Orangutans have large, grasping feet with opposable toes that assist in climbing and gripping branches.
Hair: Orangutans have long, shaggy hair covering their bodies. The hair is primarily reddish-brown in color, which gives them their name (“orangutan” means “person of the forest” in Malay). Their hair provides insulation and protection from rain and sun.
Face and Features: Orangutans have a flat face with prominent features. Adult males develop distinctive cheek pads made of fat and muscle, which grow larger as they mature. Males also develop throat pouches that amplify their calls. Both males and females have small ears and a pronounced snout.
Teeth and Jaw: Orangutans have strong jaws and sharp, pointed teeth adapted for their plant-based diet. They have long canines, which are larger in adult males, and molars with low, rounded cusps for grinding tough plant material.
Vocalizations: Orangutans possess a specialized voice box, known as the laryngeal sac, which amplifies their calls. This adaptation allows their vocalizations, including long calls, to carry over long distances through the forest.
Brain: Orangutans have relatively large brains compared to other primates. They are highly intelligent animals known for their problem-solving abilities and complex cognitive skills.
In addition to the fun facts about Orangutans, these anatomical features enable orangutans to navigate their arboreal environment with agility and strength. Their unique adaptations reflect their specialization for life in the rainforest canopies of Southeast Asia.

The Pulsating Colors Illusion is an example of a pulsating illusion.
Pulsating illusions are visual phenomena in which a stationary image or pattern appears to pulsate or vibrate in an apparent expansion and contraction motion. These illusions create the perception of rhythmic changes in the size, brightness, or intensity of the visual stimulus, even though the stimulus itself is static.
Here are a few examples of pulsating illusions like the Pulsating Colors Illusion:
Peripheral Pulsation: This illusion occurs when a high-contrast pattern or image, such as a black and white checkerboard or concentric circles, appears to pulsate or expand and contract at the periphery of our visual field. The edges of the pattern seem to pulsate in an alternating manner, creating an impression of motion.
Troxler’s Fading: Troxler’s fading is a phenomenon in which a stationary object disappears or fades from our perception when we fixate our gaze on it for a prolonged period. As we focus on a central point, the surrounding visual stimuli, such as the edges or background, can appear to pulsate, fade, or disappear.
Mach Bands: Mach bands are an optical illusion that involves the perception of alternating bands of brightness or darkness along the edges of a gradient or transition in luminance. These bands can appear to pulsate or intensify, creating the illusion of sharp, exaggerated contrast.
Hermann Grid Illusion: The Hermann grid illusion features a grid of black squares on a white background with small white dots at the intersections. When viewing the grid, the dots may appear to pulsate or flicker due to the interaction between neighboring squares and the process of lateral inhibition in our visual system.
Scintillating Grid Illusion: The scintillating grid illusion consists of an array of white or light-colored dots arranged on a grid pattern on a dark background. When fixating on a specific intersection, the dots surrounding the fixation point may appear to pulsate or scintillate.
Pulsating illusions are thought to arise from interactions between different neural processes involved in contrast perception, lateral inhibition, and adaptation in our visual system. They highlight the dynamic nature of visual perception and how our brain processes and interprets visual information, leading to perceptual experiences of pulsating or rhythmic motion in static stimuli.
How Does the Pulsating Colors Illusion Work?
The Pulsating Colors Illusion is an example of a pulsating illusion.
Pulsating illusions like the Pulsating Colors Illusion work by exploiting various mechanisms and processes within our visual system. While the exact mechanisms are not fully understood, there are several theories that help explain how these illusions work. Here are a few possible explanations:
Lateral Inhibition: Pulsating illusions, such as the peripheral pulsation or Mach bands, are thought to involve lateral inhibition, which is a fundamental process in our visual system. Lateral inhibition occurs when neurons in the visual system inhibit the activity of neighboring neurons, enhancing the contrast and edge detection. In the presence of high-contrast patterns or gradients, this lateral inhibition can lead to the perception of pulsating or oscillating brightness or intensity along the edges.
Adaptation and Contrast: Adaptation plays a role in pulsating illusions as well. Prolonged exposure to a visual stimulus can lead to adaptation, where neurons in the visual system become less responsive to the stimulus. When viewing the static pattern after adaptation, the perception of pulsation or fluctuation arises as the neurons recover from the adaptation state and regain their sensitivity. This recovery process creates a perceptual experience of rhythmic changes in size, brightness, or intensity.
Neural Resonance: Some theories propose that pulsating illusions may involve neural resonance, where specific frequencies or spatial patterns of neural activity in the visual system resonate with certain characteristics of the visual stimuli. This resonance could result in oscillatory or pulsating perceptual experiences.
Attention and Eye Movements: Attention and eye movements can also influence pulsating illusions. Shifting attention or making small eye movements can affect the perception of the illusion, potentially amplifying or diminishing the pulsating effect.
These explanations suggest that pulsating illusions like the Pulsating Colors Illusion arise from interactions between neural processes related to contrast perception, lateral inhibition, adaptation, and attention within our visual system. These processes contribute to the perception of rhythmic changes in the stimuli, even when the stimuli themselves are static. However, research in this area is ongoing, and further studies are needed to fully understand the underlying mechanisms of pulsating illusions.
Some Similar Illusions
The Pulsating Colors Illusion is an example of a pulsating illusion.
There are several illusions that share similarities with pulsating illusions in terms of their effects on visual perception. Here are a few examples of similar illusions to the Pulsating Colors Illusion:
Flicker Illusion: The flicker illusion involves the perception of flickering or pulsating motion in a static image or pattern. It occurs when different parts of an image or pattern are alternated rapidly, creating an illusion of movement or pulsation.
Flashed Face Distortion Effect: This illusion occurs when two aligned faces are presented alternately with a rapid flashing pattern. The faces appear to distort and pulsate, with exaggerated facial features and a sense of movement.
Phantom Illusion: The phantom illusion is characterized by the perception of a moving object in the absence of actual motion. It occurs when multiple stationary objects, such as discs or dots, are presented at regular intervals, creating the illusion of a smoothly moving object.
Neon Color Spreading: Neon color spreading is an illusion where a bright color appears to spread and overlap onto surrounding areas of lower brightness or contrasting color. The color spreading effect can create the perception of pulsating or fluctuating boundaries between different colors or surfaces.
Pulfrich Effect: The Pulfrich effect is a perceptual phenomenon that occurs when viewing a pendulum or moving object through a darkened lens or filter. The object appears to swing back and forth in a plane that is not actually present, creating a pulsating or oscillating motion.
These illusions, like the Pulsating Colors Illusion, demonstrate the complex nature of visual perception and how our brains interpret and process visual information. They often involve the interaction of contrast, adaptation, attention, and temporal dynamics within the visual system to create perceptual experiences that deviate from physical reality.
