How the Brain Learns That Earmuffs Are Not Valuable at the Beach

January 19, 2021

A new study from the University of Tsukuba in Japan and the NEI reveals how the brain learns to place different values on objects depending on the environmental context.

A Rift in the Retina May Help Repair the Optic Nerve

January 14, 2021

In experiments in mouse tissues and human cells, Johns Hopkins Medicine researchers say they have found that removing a membrane that lines the back of the eye may improve the success rate for regrowing nerve cells damaged by blinding diseases.

A Niche for the Eye

January 12, 2021

Research from the Stowers Institute suggests that the ciliary body might be key to detecting eye diseases before vision is impaired.

Zika Virus Affects Eye Development Before But Not After Birth

December 18, 2020

A new study has found that Zika infection during the first trimester of pregnancy can impact fetal retinal development and cause congenital ocular anomalies. The virus does not appear to affect ocular growth postnatally.

Study in mice shows genes may be altered through drug repurposing

December 17, 2020

Researchers at the University of Illinois Chicago have published a study showing a promising approach to using drug repurposing to treat genetic diseases.

New approach reveals structure and function of individual synapses

December 16, 2020

An interdisciplinary team of scientists at the Max Planck Florida Institute for Neuroscience have developed a novel approach to measure the activity and strength of individual synapses that drive a neuron’s response to sensory input.
