RESPONSES OF NEURONS IN THE VENTROLATERAL ORBITAL CORTEX TO NOXIOUS CUTANEOUS STIMULATION IN A RAT MODEL OF PERIPHERAL MONONEUROPATHY

The responses of ventrolateral orbital cortex neurons to noxious cold pressor were compared in rats with loose ligatures tied around their s ciatic nerve with those in rats in which the sciatic nerve was exposed but not ligated. In ligated rats more cells responded to cold pressor and their average afterdischarges ware longer. There were no differen ces in the background firing rate or the magnitude of response to the cold pressor between the two groups.
