title: [Comparison of effects of EA at "hegu" on nociceptive responses of NRM neurons to noxious stimulation of the face and tail].
abstract: The experiments were performed on the rats. Unit discharges in NRM and their nociceptive responses to dental pulp and tail noxious stimulations were recorded extracellularly with glass microelectrodes. We observed that EA at the "Hegu" acupoint could increase spontaneous discharges of NRM neurons and inhibit their nociceptive responses to noxious stimulation acting on dental pulp and tail. It is interestingly noted that the inhibitory effect of EA on noxious stimulation applying on the pulp is stronger than the tail.
