Transient and rapid change in the electrical potential at the surface of a cell.
When a neuron is activated either by an "order" received from the brain or by "information" received from the periphery (an image, a pain, a sound....) an exchange of calcium and sodium ions takes place between the inside and outside of the neuron. This exchange of ions causes an electric current, the action potential, which travels along the axon of the neuron to another neuron.
