Star-Shaped Brain Cells May Play a Critical Role in Glaucoma

June 23, 2020

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 look to the eye for insights about the brain

June 23, 2020

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.

Inhibitory Interneurons in Hippocampus Excite the Developing Brain

June 12, 2020

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.

Faces, bodies, spiders, and radios: How the brain represents visual objects

June 5, 2020

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.

'Time is vision' after a stroke

May 27, 2020

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

May 18, 2020

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

May 14, 2020

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

April 30, 2020

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

April 7, 2020

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

March 13, 2020

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.
