Effects of electroacupuncture (EAP) on the responses of different functional types of neurons of the oral trigeminal nucleus (OTN) by nociceptive and non-nociceptive stimulation were studied in acute experiments on adult cats. It was demonstrated that the main part of neurons of the OTN is a wide dynamic range of neurons. Characteristic feature of the OTN is neurons with low-threshold pulp afferent input. EAP inhibit nociceptive responses of neurons (preferentially nonspecific neurons), while responses to non-nociceptive stimulation are not changed at all. The results are discussed from the point of view that OTN takes part in nociceptive and non-nociceptive reactions.
