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.
