After a brain injury, cells that normally nourish nerves may actually kill them instead, a new NYU study in rodents finds. This “reactive” phenomenon may be the driving factor behind neurodegenerative diseases like glaucoma, a leading cause of blindness.

Researchers seeking to unravel the mysteries of how our amazingly complex brains do what they do, often start with the eye. The retina, the light-sensing tissue at the back of the eye has long been a model for scientists to explore how the brain works.

A new study from the George Washington University finds that in some parts of the developing brain, the inhibitory neurons cause excitation rather than suppression of brain activity, which could have implications for the treatment of neonatal seizures.

Caltech researchers have combined tools from machine learning and neuroscience to discover that the brain uses a mathematical system to organize visual objects according to their principal components. The work was published June 3 in Nature.

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.

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.

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.

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.

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

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.
