While people with aphantasia lack visual imagery ability, they have intact spatial memory. Findings suggest mental imagery recall and spatial memory may be stored differently in the brain.
It may be harder to recognize familiar faces when they wear a surgical mask to protect against COVID-19, a new study reports. Researchers noted a 15% drop in the ability for people to recognize faces when they were masked.
Study links brain structure to color perceptual function. Microscopy revealed 'hue maps,' or color palettes, in the brain that are spectrally organized arrangements of hue responses.
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.
