Restoring nerve-muscle communication in ALS

Patients with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, lose muscle control as nerve cells or neurons in the brain and spinal cord degenerate and can no longer send signals to muscles. Previous ...

Ultra-thin fibres designed to protect nerves after brain surgery

Brain surgery poses a major threat to nerve cells. Even slight injuries can kill the sensitive cells. The drug nimodipine could help prevent this. It is currently being used to treat cerebral haemorrhages. The drug relaxes ...

Nerve

A nerve is an enclosed, cable-like bundle of peripheral axons (the long, slender projections of neurons). A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons. Nerves are found only in the peripheral nervous system. In the central nervous system, the analogous structures are known as tracts. Neurons are sometimes called nerve cells, though this term is technically inaccurate since many neurons do not form nerves, and nerves also include non-neuronal Schwann cells that coat the axons in myelin.
