Researchers at Johns Hopkins University created 'visual anagrams' using AI to study how people mentally process visual information. The findings reveal classic real-world size effects, even when objects are rotated versions of the same image.
Researchers identified IC-encoder neurons that drive pattern completion and recurrent neural activity in the brain. The findings have implications for understanding neuropsychiatric disorders like schizophrenia.
Researchers found that medical imaging experts can solve common optical illusions, including judging the size of objects. Training to improve visual perception can also make experts less susceptible to these illusions. This study has implications for training medical image analysts.
A new analysis of 105-year-old data found that while dazzle camouflage had some effect, the 'horizon effect' had a much greater influence on confusing enemy ships. The study, led by Aston University researchers, showed that when people looked at a ship in the distance, they significantly underestimated its direction of travel.
Researchers found that moth wings with forward-facing eyespots are more effective at deterring predators than those with concentric circle patterns. The study suggests that the direction of gaze affects the predator's motivation to attack, supporting the idea that eyespots are used to maintain eye contact with predators.
Researchers are studying visual regions of the mouse brain as animals see and respond to different pictures or movies, with projects led by Vanderbilt University, UC Berkeley, and York University. The study aims to uncover how neurons react to optical illusions and how the brain interprets sensory information.
Researchers at Salk Institute discovered that neurons deep in the brain's cortex process information from borders first, then send clues back to upstream areas. This supports the importance of the 'feedback' pathway for deciphering borders.
The National Institute for Materials Science in Japan has developed an ionic artificial vision device capable of increasing edge contrast between dark and light areas like human vision. This device uses ionic migration and interaction within solids to mimic human optical illusions without software.
A new study by the University of Plymouth and Essex found that many adults struggle to imagine their own visual perception as a flat image, resisting the idea of 'corrected' vision. When shown two lines with different lengths, participants often judged them as equal in length, despite being able to see one as longer when viewed on camera.
Researchers used a well-known optical illusion to isolate key clusters of neurons in zebrafish, finding only a dozen or so neurons required for motion perception. The study aims to understand how these neurons are wired within the neural circuit and their connections with visual input.
Scientists at Yale University found that flies perceive motion in static images similarly to humans, using a shared strategy for motion detection. By analyzing specific neuron types and behavior, the researchers developed a theory explaining how optical illusions work, which may also apply to human visual systems.
Researchers developed a neural-network model that perceives contextual optical illusions like humans, advancing knowledge of human visual system. The model includes feedback connections between neurons, which improve artificial vision by addressing context-dependent weaknesses.
A functional magnetic resonance imaging (fMRI) study found that The Dress activates frontal and parietal brain areas, depending on perception. Researchers identified differential brain activity in participants perceiving the dress as white-gold versus black-blue.
Research at the University of Rochester shows that our brains apply an algorithm to track objects, including baseballs, even when they move outside our visual field. This understanding can help hitters better anticipate a curveball's trajectory.
Astronomers have discovered that the Sun's corona loops appear as a constant width due to an optical illusion, but in reality, they are tapered structures. This finding has significant implications for coronal heating models.
Researchers at Queen Mary University of London found that an optical illusion captures attention more strongly than other visual tests due to reflexive brain processing. The study suggests that the brain rapidly processes visual clues to guide where eyes look, influencing what we see.
Researchers used two well-known optical illusions to study how the brain assesses relative size, revealing that environmental clues affect perception after three-dimensional image processing. The Ponzo illusion was found to hold true regardless of eye use or presentation order.
Researchers found that individual volunteers' perceptions of optical illusions varied greatly due to differences in brain size. The primary visual cortex area affects the extent to which we see visual illusions.
Researchers found that specific brain regions show similar patterns of activity when viewing ambiguous images, implying these regions contribute to conscious experience. The study's findings may help understand disorders like dyslexia by providing insight into the functional role of motion-perception areas in the brain.
