How Traumatic Experiences Can Leave Their Mark on a Person’s Eyes

Pupillary response in those with PTSD differs from people who have not experienced traumatic events. The pupils of those with PTSD failed to show sharp constriction caused by light changes, and more enlargement when exposed to emotional stimuli that other participants. Patients with PTSD not only showed an exaggerated response to threatening stimuli but also to stimuli that depicted positive images.

Is What I See, What I Imagine? The Neural Overlap Between Vision and Imagination

Using artificial intelligence and neuroimaging, researchers have identified a link between mental imagery and vision. The brain uses similar visual areas for mental imagery and vision but uses low-level visual areas less precisely for mental imagery than vision.

Scientists Discover a New Connection Between the Eyes and Touch

Micro-saccades, or tiny eye movements, can be used as an index of our ability to anticipate relevant information in the environment, independent of the information's sensory modality.

Being ‘mind-blind’ may make remembering, dreaming and imagining harder

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.

A man who can’t see numbers provides new insight into awareness

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.

Study sheds light on a classic visual illusion

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.

Neurons can shift how they process information about motion

When it comes to processing information about motion, neurons in the ventral intraparietal area of the brain are more flexible in switching between reference frames. The findings could be used to develop neural prosthetics designed for motion control.

Our visual world of color is largely incorrect

People are oblivious to change when color is removed from peripheral vision. Research reports the brain likely fills in for much of our perceptual experience when it comes to seeing the entire picture in color.
