First-ever restoration of vision achieved in mice

Experiments conducted under the leadership of a Stanford University School of Medicine investigator have succeeded, for the first time, in restoring multiple key aspects of vision in mammals.

Targeted brain stimulation aids stroke recovery in mice

When investigators at the Stanford University School of Medicine applied light-driven stimulation to nerve cells in the brains of mice that had suffered strokes several days earlier, the mice showed significantly greater ...

Repairing nerves requires prods of protein

When there's damage in the body, our cells call for help. UConn brain researchers just found a new way cells do this—like in the old AT&T ad campaign, they reach out and touch someone.

Brain damage caused by plasticisers

The plasticisers contained in many everyday objects can impair important brain functions in humans. Biologists from the University of Bayreuth warn of this danger in an article in Communications Biology. Their study shows ...

Designer cytokine makes paralyzed mice walk again

To date, paralysis resulting from spinal cord damage has been irreparable. With a new therapeutic approach, scientists from the Department for Cell Physiology at Ruhr-Universität Bochum (RUB) headed by Professor Dietmar ...

Star-shaped brain cells may play a critical role in glaucoma

After a brain injury, cells that normally nourish nerves may actually kill them instead, a new study in rodents finds. This "reactive" phenomenon may be the driving factor behind neurodegenerative diseases like glaucoma, ...

Nerve injury

There is no single classification system that can describe all the many variations of nerve injury. Most systems attempt to correlate the degree of injury with symptoms, pathology and prognosis. In 1943, Seddon introduced a classification of nerve injuries based on three main types of nerve fiber injury and whether there is continuity of the nerve. The three types are : neurapraxia, axonotmesis and neurotmesis.
