[Role of the medial region of the hypothalamus in regulating the activity of the respiratory neurons of the medulla oblongata].
The influence of high frequency stimulation of postero- and anteromedial hypothalamic regions on the activity of single neurons of the bulbar respiratory center was studied in anesthetized cats with normal respiration. No strictly localized facilitatory or inhibitory points were found in these regions. Excitatory as well as inhibitory descending pathways were activated by the hypothalamic stimulation. The effect was mainly facilitating. The excitatory and inhibitory influences of the medial hypothalamus modulated spike activity of both inspiratory and expiratory neurons of the bulbar respiratory center. Some functional aspects of the mechanism for hypothalamic regulation of the activity of bulbar respiratory neurons are discussed.
