Neural circuits within the retina are able to generate the information required to predict the movement and path of an object before visual signals leave the eye, researchers report.
Face pareidolia, a phenomenon where the brain is tricked into seeing human faces in inanimate objects, may occur as a result of the brain processing the perceived facial expression in the same sequential way it perceives a human face.
Researchers say the order in which your senses interact with food items impacts how much you enjoy your meal.
People with depression often experience problems with visual perception. Researchers report issues with visual perception are likely linked to information processing differences in the cerebral cortex.
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.
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.
