afterpotential
afterpotential[′af·tərpə¦ten·chəl] (neuroscience) A small positive or negative wave that follows and is dependent on the main spike potential, seen in the oscillograph tracing of an action potential passing along a nerve. afterpotential
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.af·ter·po·ten·tial , after-potential (af'tĕr-pŏ-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. af·ter·po·ten·tial , after-potential (af'tĕr-pŏ-ten'shăl) The small change in electrical potential in a stimulated nerve that follows the main, or spike, potential. |
