afterpotential

 [af″ter-po-ten´shul]
an electrical event that follows and is caused by preceding action potentials. Also written after-potential.

af·ter·po·ten·tial

(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.

afterpotential

/af·ter·po·ten·tial/ (-po-ten″shul) the small action potential generated following termination of the spike or main potential; it has negative and (paradoxically named) positive phases, the latter being in fact more negative than the resting potential.
