How Do We Prioritize What We See?

A new study by a team of neuroscientists has discovered that one specific region, the occipital cortex, plays a causal role in piloting our attention to manage the intake of images.

NIH-funded study identifies stem cells in optic nerve

A National Eye Institute-funded study has identified a type of stem cell called a neural progenitor cell, in a region of the optic nerve, which connects the eye to the brain.

Ultra-low power brain implants find meaningful signal in grey matter noise

University of Michigan researchers have dramatically reduced the power requirements of neural interfaces while improving their accuracy—a discovery that could lead to long-lasting brain implants.

Neurons are genetically programmed to have long lives

Researchers reveal a mechanism by which long-term survival of neurons is intrinsically programmed during development.
IL-17A acts on Th17 cells to produce anti-inflammatory response

Dual role discovered for molecule involved in autoimmune eye disease

The inflammatory molecule interleukin-17A (IL-17A) triggers immune cells that in turn reduce IL-17A’s pro-inflammatory activity, according to a new NEI study.

Study points to potential new approach to treating neurodegenerative diseases like glaucoma and Alzheimer’s disease

Researchers have shown for the first time that when one optic nerve in the eye is damaged, as in glaucoma, the opposite optic nerve comes to the rescue by sharing its metabolic energy.

Study helps to settle debate on roles of REM and non-REM sleep in visual learning

A study by a team of Brown University researchers sheds new light on the complementary roles of REM and non-REM sleep in visual perceptual learning.

Vision loss in children whose eyesight may be 20/20 requires new diagnostic and teaching strategies

Cerebral (cortical) visual impairment (CVI) is a condition that interferes with the ability of the brain to process information from the eyes, and it has become a leading cause of visual impairment in the U.S.

Study finds that special filters in glasses can help the color blind see colors better

A new study found that special patented glasses engineered with technically advanced spectral notch filters enhance color vision for those with the most common types of red-green color vision deficiency (“anomalous trichromacy”).

More than Meets the Eye

A new study led by researchers at Harvard Medical School and the VA Boston Healthcare System shows that face blindness may arise from deficits beyond visual perception and appears to involve glitches in retrieving various contextual cues from memory.
