[Disappearance of the electroacupuncture effect in rabbits following destruction of the dorsomedial hypothalamus]
In ten experiments on 10 awake rabbits it was shown that the lesion of dorsomedial hypothalamic nuclei induced blocking of the suppression effect of the evoked potential of the thalamus median center on electrocutaneous stimuli under electroacupuncture. At the same time the lesion of the nucleus raphe magnus did not influence the electroacupunture effect. It is suggested that the electroacupuncture is mediated by the hypothalamic analgesic system.
