title: [Bioelectric activity of the hypothalamus of adult and old rabbits during prolonged vasopressin administration].
abstract: In adult and old rabbits, the bioelectrical activity of supraotic, ventromedial and mamillary hypothalamic nuclei was studied after chronic (30 days) administration of vasopressin (0.2 U/kg of body weight). The hormone altered considerably the bioelectrical activity, these changes being uneven in various hypothalamic areas. Quantitative and qualitative differences of the changes were found in animals of different age. These changes of the hypothalamic bioelectrical activity seem to play an important role in the alterations of hemodynamic indices observed during chronic vasopressin administration.
