Neurophysiological justification of the G. F. Lang hypothesis about the occurrence of essential hypertension

This article is an analysis of modern data on the morphological, functional and neurochemical organization of the central mechanisms of blood circulation regulation, the violation of which can cause the development of essential hypertension. The data indicating the validity of the hypothesis of G.F. Lang that prolonged emotional stress leads to a violation of the neuronal activity of the hypothalamus structures are presented. The article describes the morphological connections of the hypothalamus with the neurons of the ventrolateral region of the medulla oblongata and the structures of the spinal cord that provide neurogenic vascular tone. The evidence of convergence of axons of neurons of the paraventricular nucleus of the hypothalamus on the preganglionic neurons of the spinal cord is presented. Neurochemical processes in the vasomotor center of the medulla oblongata are considered, morphological changes of preganglionic sympathetic neurons in experimental arterial hypertension are indicated.
