Abstract

Electrical stimulation of various loci in the hypothalamus, septum, or rostral forebrain of 23 female Sprague-Dawley rats frequently produced an increase, and occasionally a decrease, in body temperature. Stimulation while the Ss were working for radiant heat reinforcement in a cold environment rarely affected the rate of response or reinforcement. There was no consistent relation between the magnitude of the temperature change induced by electrical stimulation and other behaviors such as grooming, huddling, and self-stimulation. Thus, electrical stimulation effected changes in body temperature but did not affect motivational components of temperature regulation.
