Intracentral connections of the brain structures participating in the regulation of blood flow.

In this study, we conducted an investigation into the characteristics of hemodynamic reactions during electrical stimulation of the structures of the hypothalamus and during simultaneous stimulation of the sinus nerve and the hypothalamus in anesthetized cats. We also investigated the monosynaptic connections of the hypothalamus with the structures of the brain stem and spinal cord. The possible influence of the hypothalamus, following the activation of various descending pathways (both through the bulbar level of regulation and by-passing it), upon the efferent component of the regulation of blood circulation is discussed; a scheme of intracentral connections of the brain structures participating in the regulation of blood circulation is presented.
