'Time is vision' after a stroke

A person who has a stroke that causes vision loss is often told there is nothing they can do to improve or regain the vision they have lost. But research from the University of Rochester may offer hope to stroke patients in regaining vision.

Early visual experience drives precise alignment of cortical networks critical for binocular vision

Researchers at the Max Planck Florida Institute for Neuroscience identify three distinct cortical representations that develop independent of visual experience but undergo experience-dependent reshaping, an essential part of cortical network maturation.

Retinal Texture Could Provide Early Biomarker Of Alzheimer’s Disease

Biomedical engineers at Duke University have devised a new imaging device capable of measuring the various layers of the retina at the back of the eye, which could be used to detect Alzheimer's disease.

Eyes send an unexpected signal to the brain

New research, led by Northwestern University, has found that a subset of retinal neurons sends inhibitory signals to the brain. Before, researchers believed the eye only sends excitatory signals.

It’s now or never: Visual events have 100 milliseconds to hit brain target or go unnoticed

Researchers at the National Eye Institute (NEI) have defined a crucial window of time that mice need to key in on visual events.

Therapy could improve, prolong sight in those suffering vision loss

Millions of Americans are progressively losing their sight as cells in their eyes deteriorate, but a new therapy developed by researchers at the University of California, Berkeley, could help prolong useful vision and delay total blindness.

A new model of vision

Computer model of face processing could reveal how the brain produces richly detailed visual representations so quickly.

Earliest look at newborns' visual cortex reveals the minds babies are born with

According to a study from Emory University, as young as six days a baby’s brain appears hardwired for the specialized tasks of seeing faces and seeing places.

Let there be 'circadian' light

Researchers at UW Medicine have decoded what makes good lighting – lighting capable of stimulating the cone photoreceptor inputs to specific neurons in the eye that regulate circadian rhythms.

Fralin Biomedical Research Institute scientists shed light on surprising visual development patterns

In a new study from Virginia Tech, neuroscientists reveal a surprising clue about how the intricate visual processing system forms during early brain development.
