Visual Neuroscience
Visual Neuroscience news articles cover science research into visual cortex, vision, visual disorders, blindness, brain processing of visual cues, facial recognition and research related to how eyes and brains function.
Older adults with visual impairments are 1.3 times more likely to develop mild cognitive impairment, often considered a precursor to Alzheimer's disease, than those with no significant vision loss. Read More
Researchers propose a new theory of what happens in the brain when we experience familiar seeming visual stimuli. The theory, dubbed sensory referenced suppression, suggests the brain understands different levels of activation expected for sensory input and corrects for it, leaving behind the signal for familiarity.

When people make eye contact with another person, their attention is immediately solicited and this causes a distortion in temporal perception. However, the shift in time perception does not change when people glance at non-social items or objects. Read More
Viewing a subliminal image of their own faces, participants showed an increase in activity in the dopamine reward pathway in the brain. Findings shed new light on the underlying neural processes of self facial recognition. Read More
Smoking marijuana affects several key visual functions, including 3D vision and contrast sensitivity. However, 90% of cannabis users believe the drug has either no, or minimal, effect on their visual abilities. Read More
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. Read More
People who suffer from dry eye disease symptoms report visual problems, increased depression and anxiety, and mobility issues. Dry eye disease, researchers say, can have a negative impact on the overall quality of life for sufferers. Read More
Exposing retinal pigment epithelium cells in mouse models to amyloid-beta resulted in retinal pathologies similar to those seen in human age-related macular degeneration. Read More

Autonomic mimicry in human social interactions is significant, a new study reports. Researchers found in computer facial simulations where the pupils were dilated, test subjects trusted the simulated face more and mimicked the pupillary response. Read More
Meta-analysis reveals those who have visual impairments or are blind have a higher risk of mortality compared to peers with better vision. The study found mortality risk was 29% higher in those with mild visual impairment and rose to 89% higher for those with severe visual impairments. Read More
A new retinal implant that works in conjunction with camera-equipped smart glasses and a microcomputer provides blind people with "artificial vision" by stimulating retinal cells. Read More
