Researchers link a rabbit retina to a chip in vitro

Nystagmus is a genetically transmitted disease that causes an uncontrolled, back-and-forth twitching of the eyeball. Roughly one in every 1,500 men suffer from it. But before now, we did not know that this twitching is caused ...

Myelin cells swing along blood vessels to traverse the brain

The cells that create myelin, a fatty material that insulates nerve fibers in the brain's white matter, migrate into the developing brain by climbing and swinging on blood vessels, according to new research led by UC San ...

Drug 'cocktail' could restore vision in optic nerve injury

Research from Boston Children's Hospital suggests the possibility of restoring at least some visual function in people blinded by optic nerve damage from glaucoma, estimated to affect more than 4 million Americans, or from ...

Gene could hold key to treating Parkinson's disease

Researchers at King's College London have identified a new gene linked to nerve function, which could provide a treatment target for 'switching off' the gene in people with neurodegenerative diseases such as Parkinson's disease.

Pain is in the brain

Chronic pain results from disease or trauma to the nervous system. Damaged nerve fibres with heightened responses to normal stimuli send incorrect messages to pain centres in the brain. This phenomenon, called "peripheral ...
