title: [Afferent projections of the aortic nerve onto different portions of the hypothalamic region].
abstract: Reactions of the neurons of the anterior, middle, and the posterior hypothalamus in response to electrical stimulation of the aortic nerve were studied. Two groups of neurons were distinguished in the pressor zones of the hypothalamic region. Changes of the neuron pulse activity preceded the reduction of the arterial pressure arising in response to the aortic nerve stimulation. Changes in the activity of the neurons of another group followed the arterial pressure reduction. A conclusion was drawn that excitations caused by stimulation of the aortic depressor nerves and the afferent influences, coursing during the depressor reaction from the baroreceptors of the vascular bed, spread to the neurons of the supraoptic, paraventricular, and the ventro-medial nuclei of the hypothalamus, the anterior and the lateral hypothalamic field, and the supramamillary region.
