Afterdischarge

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.

Additionally, due to the afterdischarge effect noted by Mandell, this pattern progressively increases the body's tolerance for higher levels of energy.
Rats were stimulated daily and seizure class (Racine scale) and afterdischarge duration (ADD) were determined following each stimulation.
Mandell (1980) discusses the physiology of transcendence, suggesting that a variety of altered states, including mystical, ecstatic, and spiritual experiences, may be manifestations of a brain-wave pattern featuring high-voltage, slow-wave hippocampal-septal hypersynchrony (HSHH) that lasts for long periods of afterdischarge.
