Cerebral temperature was continuously recorded in male rats during sexual activity. The temperature showed a persistent increase in the presence of females and a relatively brief, rapid increase during sexual intromission. Cerebral temperature may be usable as a sensitive measure of immediate and persisting motivational effects of transitory and longterm conditions of stimulation.
