Reconnecting Eye to Brain

Michael Crair, Yale University, and Carol Mason, Columbia University, have co-authored a report published online today in the Journal of Neuroscience.

Visual cortex plays role in plasticity of eye movement reflex

By peering into the eyes of mice and tracking their ocular movements, researchers made an unexpected discovery: the visual cortex – a region of the brain known to process sensory information – plays a key role...

Six teams seek to identify biological factors that influence neural regeneration

The National Institutes of Health will fund six projects to identify biological factors that affect neural regeneration in the retina.

NIH Vision Scientists Test Theory of How Rods in our Retina Originated

Retinas from our earliest vertebrate ancestors had cone-like photoreceptors, presumably allowing them to see in daylight, but little ability to see at night.

Neuronal Feedback Could Change What We "See"

The brain reacting to feedback between neurons in different parts of the visual system could explain the mechanism behind optical illusions.

Before Retinal Cells Die, They Regenerate, Penn Vet Blindness Study Finds

Researchers at the University of Pennsylvania showed that in a form of canine blindness retinal cells continue to differentiate for a period of time early in a dog’s life before overwhelming cell death caused the retina to degenerate.

Discovery Identifies New RX Target for Age-related Macular Degeneration & Alzheimer's

Researchers at LSU Health New Orleans have shown that a protein critical to the body’s ability to remove waste products from the brain and retina is diminished in age-related macular degeneration.

The Brain’s Gardeners: Immune Cells ‘Prune’ Connections Between Neurons

A new study by at the University of Rochester shows that cells normally associated with protecting the brain from infection and injury also play an important role in rewiring the connections between nerve cells.

A day in the life of a synapse reveals new facets of the adult brain

A new study, funded in part by NEI, sheds light on the innate plasticity of the adult brain at its most fundamental level — the synapse.

Researchers Uncover “Predictive Neuron Orchestra” Behind Looking and Reaching Movements

A new study from NYU enhances our understanding of the decision-making process, potentially offering insights into different forms of mental illness in which this dynamic is typically impaired.
