Using cats anesthetized with urethane and chloralose, we studied the effect of conditioning stimulation applied to the fornix (Fx) on the response of nociceptive neurons in the intralaminar nuclei and in the nucleus ventralis posteromedialis (VPM). In one third of the intralaminar neurons, conditioning Fx stimulation at an intensity of less than 1mA inhibited responses to peripheral input and/or to electrical stjmulation of the tract. Conditioning stimulation of the Fx did not inhibit the response to electrical stimulation in any of the VPM neurons. The results suggest that nociceptive neurons in the intralaminar nuclei are inhibited following conditioning stimulalion of the Fx. This inhibition arising from the Fx acts mainly at the thalamic level of the medial pain pathway.
