Myelin exploits phase transitions to drive it's assembly
The ability to construct complex myelin sheaths around axons is one of the greatest vertebrate inventions since the hinged jaw.

(Medical Xpress)—Pioneering experiments back in 1982 by Tasaki and Iwasa at the NIH revealed that action potentials in neurons are more than just the electrical blips that physiologists readily amplify and record. These ...
(Medical Xpress)—When minor wounds heal, the fine nerve endings that sense touch, or control sweating, are usually able to regrow. Like many processes in the body, the ability to regenerate new tissues changes throughout ...
(Medical Xpress)—Neurons have developed elaborate mechanisms for transporting critical components, like transmitter-laden vesicles, down their axons to the synaptic terminations. An axon in a blue whale may be several meters ...
A new study out today in the journal Science turns two decades of understanding about how brain cells communicate on its head. The study demonstrates that the tripartite synapse – a model long accepted by the scientific ...

(Medical Xpress) -- In the event of the spinal cord injury, the long nerve cell filaments, the axons, may become severed. For quite some time now, scientists have been investigating whether these axons can be stimulated to ...

Traumatic injuries to the peripheral nervous system are a leading cause of disability, especially in patients with proximal peripheral nerve injury. It's hard to regenerate and regain normal function in a short period, and ...

A complex network of nerve fibers and synapses in the brain is responsible for transmission of information. When a nerve cell is stimulated, it generates signals in the form of electrochemical impulses, which propagate along ...

Repeat concussions, also referred to as repetitive mild traumatic brain injury, can lead to chronic traumatic encephalopathy (CTE) and raise the risk of Alzheimer's disease. However, some people who experience repetitive ...
