Scientists unravel the function of a sight-saving growth factor

June 16, 2021

Researchers at the National Eye Institute (NEI) have determined how certain short protein fragments, called peptides, can protect neuronal cells found in the light-sensing retina layer at the back of the eye.

What makes us sneeze?

June 15, 2021

A team led by researchers at Washington University School of Medicine in St. Louis has identified, in mice, specific cells and proteins that control the sneeze reflex.

As novel sights become familiar, different brain rhythms, neurons take over

June 9, 2021

A new study by researchers at MIT’s Picower Institute for Learning and Memory substantially advances understanding of how a mammalian brain enables “visual recognition memory.”

High caffeine consumption may be associated with increased risk of blinding eye disease

June 7, 2021

Consuming large amounts of daily caffeine may increase the risk of glaucoma more than three-fold for those with a genetic predisposition to higher eye pressure according to an international, multi-center study.

International coalition classifies 25 subtypes of uveitis, an inflammatory eye disease

June 7, 2021

An international coalition of eye researchers used machine learning to develop classification criteria for 25 of the most common types of uveitis, a collection of over 30 diseases characterized by inflammation inside the eye.

Brain tumors caused by normal neuron activity in mice predisposed to such tumors

May 26, 2021

A study by researchers at Washington University School of Medicine in St. Louis and Stanford University School of Medicine shows that the normal day-to-day activity of neurons can drive the formation and growth of brain tumors.

Vision researchers at Wayne State discover new therapy to treat eye infections

May 20, 2021

Researchers at the Wayne State University School of Medicine have discovered that a metabolite called itaconate produced during cellular metabolism plays a role in protecting the eye from abnormal inflammation during infection.

AI Spots Individual Neurons in the Eye Better than Human Experts

May 4, 2021

A new combination of optical coherence tomography (OCT), adaptive optics and deep neural networks should enable better diagnosis and monitoring for neuron-damaging eye and brain diseases like glaucoma.

New research assesses naturalistic driving techniques to link vision impairment and traffic accidents

May 4, 2021

New research from the University of Alabama at Birmingham has used naturalistic driving techniques to link vision impairment in older drivers to at-fault crashes and near-crashes.

A new theory for what’s happening in the brain when something looks familiar

May 4, 2021

University of Pennsylvania researchers propose a new theory for how the brain understands the level of activation expected from a sensory input and corrects for it, leaving behind the signal for familiarity.
