It seems that flies are as susceptible to optical illusions as humans. Turning on and off some neurons that govern motion detection in flies, researchers were able to alter the insects' perception of illusory motion.
Aphantasia, a disorder in which people are lack the ability to mentally visualize imagery, is also associated with a widespread pattern of changes to other important cognitive processes. Many with aphantasia report a reduced ability to recall past events, imagine the future, and dream.
The study of a man with a neurodegenerative disease that has robbed his ability to see certain numbers sheds light on how the brain processes information without any visual awareness of the stimuli.
A new study sheds light on why we get tricked by a classic optical illusion. Researchers found brightness estimations occur before visual information reaches the visual cortex, probably originating in the retina.
Study provides an answer to the age-old philosophical question of whether people can see the world objectively. In terms of visual perception, the answer is no.
Neuroimaging study sheds new light on how we perceive colors. Activity in higher visual cortex areas matched the colors test subjects saw.
Prediction errors play a role in the context of dynamic perceptual events that take place within fractions of a second. Findings support the hypothesis that visual perception occurs as a result of a decision process.
Visually represented information is a functional part of conceptual knowledge. The extend of the visual representations is influenced by visual experience.
Contextual information, especially space and sequence, contributes to the distortion of perception in short-term memory.
Study provides new evidence supporting the theory that perceptual limitations are caused by a correlated noise in neural activity.
Boundary contraction may be as common as boundary extension, and whether something appears zoomed in or out depends on the properties of the image.
