Abstract This experiment tested the effect of an injection of orexin A into the diagonal band of Broca on the sympathetic activity and body temperature. Concentration of glycerol into white fat of lumbar region, firing rates of sympathetic nerves to interscapular brown adipose tissue (IBAT), IBAT and colonic temperatures, and heart rate were monitored in urethane-anesthetized male Sprague-Dawley rats for 30 min before and 150 min after injections of orexin A (0.4 and 0.7 nmol) into the diagonal band of Broca. The same variables were monitored in control rats with an injection of saline. The results show that orexin A increases glycerol concentration, sympathetic firing rate, IBAT and colonic temperatures, and heart rate. The saline injection did not induce any modification. These findings suggest that the diagonal band of Broca is a cerebral structure involved in the induction of the hyperthermia due to orexin A.
