What is An Action Potential?

An action potential is an electrical impulse that begins at the axon hillock (trigger zone), propagates away from the soma, and moves down the axon, synaptic knob, and synapse. The action potential is triggered by a depolarization of the neuron from -70mV to -55mV. This depolarization occurs when the neuron receives either repeated stimuli or … Read more
