Afterdischarge
the ability of neurons to rhythmically discharge impulses for a relatively long time after cessation of the stimulus. Usually, the stronger the stimulus and the longer its action on the receptors, the longer the afterdischarge. A short-term afterdischarge is produced by successive depolarization of the membrane of the neuron after prolonged rhythmic stimulation. A prolonged afterdischarge depends on the circulation of nerve impulses in the closed neuronal circuits of the reflex center.

A pair of GABAli neurons (cerebral A interneuron [Cr-Aint], Arshavsky et al., 1993; Norekian and Satterlie, 1993) was shown to drive a prolonged
afterdischarge in the network that controls the buccal cone appendages.
Neuronal hyperactivity has been well documented in electrophysiological studies in rodent SCI models and is characterized by increased evoked and spontaneous action potential frequencies, lowered thresholds for action potential generation, and prolonged
afterdischarge activity [52-56].
Moreover, vanillin also induced a significant shortened epileptic
afterdischarge duration (Wu et al., 1989).
