Plant-derived scavengers prowl the body for nerve toxins
The brain is forever chattering to itself, via electrical impulses sent along its hard-wired neuronal "Ethernet." These e-messages are translated into chemical transmissions, allowing communication across ...

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.
