an electrical event that follows and is caused by preceding action potentials. Also written after-potential.

(af'ter-pō-ten'shăl),
The small change in electrical potential in a stimulated nerve that follows the main, or spike, potential; it consists of an initial negative deflection followed by a positive deflection in the oscillograph record.
