Study Helps to Settle Debate on Roles of REM and Non-REM Sleep in Visual Learning

During non-REM sleep, visual areas of the brain exhibit an excitation/inhibition balance indicative of increased plasticity. REM sleep appears to be essential for people to reap the benefits of the increased plasticity that occurs during NREM sleep. Read More

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. Read More

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. Read More

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. Read More

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. Read More

The relationship between looking and listening and human emotions

A new study reveals the relationship between attentional state and emotions from pupillary reactions. Visual perception elicits emotions in all attentional state, while auditory perception elicits emotions only when attention is paid to sounds. Read More

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. Read More

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. Read More

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. Read More
