title: [Neuroendocrine mechanisms of participation of the raphe nuclei in the development of hypertensive reactions in emotional stress].
abstract: The experiments on cats and rabbits have studied electroencephalographic, endocrine and blood pressure responses to stress (5-hour immobilization with electrical foot shock) before and after coagulation of the midbrain nuclei raphe. Blood pressure and adrenal responses in advanced (4-hour) stress were elevated in intact animals, the responses attenuating after coagulation of the nuclei raphe. Background bioelectrical activity of the midbrain reticular formation and hypothalamus was found to be activated in the operated animals. Stress was followed by the reduction in bioelectrical changes of the above subcortical structures with the parallel development of "burst" activity in the dorsal hippocamp.
