... The action potential is a rapid change in the membrane potential that spreads quickly along the cell membrane of a neuron. A signal is transmitted when a STIMULUS triggers a neuron…and causes an ACTION POTENTIAL (aka nerve impulse). The action potential was discovered in 1952 by Huxley and Hodgkin a ...
