[Septal nuclei in the mechanisms of lateral hypothalamic self stimulation in rabbits].
Unilateral lesions of medial septal nucleus and lateral septal nuclei (dorsalis, intermedius, ventralis) decreased ipsilateral hypothalamic self-stimulation; the lesions of n. dorsalis, n. medialis and lateral septal nuclei (intermedius and ventralis) has the opposite effect on contralateral self-stimulation. The inhibition of ipsilateral self-stimulation was neither total nor permanent; 25-32% decrease in stimulation rate was seen, but behaviour returned to near-normal levels over a period of few days. In contrast, the augmentation of contralateral self-stimulation showed no significant change over the same period; in this case the 35-40% shift in stimulation rate was immediate and permanent. Bilateral lesions of septal nuclei had no effect if the initial level of self-stimulation rate was high and significantly increased self-stimulation.
