White matter may aid recovery from spinal cord injuries: Study

Injuries, infection and inflammatory diseases that damage the spinal cord can lead to intractable pain and disability. Some degree of recovery may be possible. The question is, how best to stimulate the regrowth and healing ...

Action potential

An action potential (or nerve impulse) is a transient alteration of the transmembrane voltage (or membrane potential) across an excitable membrane generated by the activity of voltage-gated ion channels embedded in the membrane. Action potentials play multiple roles in several types of excitable cells such as neurons, myocytes, and electrocytes. The best known action potentials are pulse-like waves of voltage that travel along axons of neurons.
