To study the role of brain serotonin in entrance into hibernation, intraventricular injections of 5,7-dihydroxytryptamine, electrolytic lesions of small parts of the median raphe nucleus, and chemical lesions of the same nucleus were undertaken on the European hamster in winter. All the lesions led to a variable decrease of serotonin levels in all parts of the brain areas examined. However, hibernation was suppressed only in those animals whose serotonergic neurons were destroyed in a small anterior part of the median raphe nucleus. Electrolytic lesions as well as chemical lesions in the other parts of the median raphe nucleus or the 5,7-dihydroxytryptamine injections into lateral ventricles do not prevent hibernation. These data suggest that in the European hamster only a specific group of serotonergic neurons of the median raphe nucleus are involved in the process of entrance into hibernation.

Stress-induced activation of median raphe serotonergic neurons in rats is potentiated by the neurotensin antagonist, SR 48692
