[Participation of reticular neurons of the cat medulla oblongata in the integration of the respiration center activity]. / Uchastie retikuliarnykh neironov prodolgovatogo mozga koshki v integrativnoi deiatel'nosti dykhatel'nogo tsentra.

Reticular neurons of the respiratory centre are divided into three groups. The 1st one is located in the medial areas and accepts afferents from chemoreceptors. The 2nd one is located in inspiratory and expiratory areas of the centre and take part in integration of afferent signals and activation of the effector mechanism. The 3rd group is present in both areas and organizes the effector activity of the centre. Electrical stimulation of the brain stem nuclei can modify reticular neurons in lateral areas.

[The interaction of the respiratory and cardiovascular systems at the level of the medulla oblongata structures]. / Vzaimodeistvie dykhatel'noi i serdechno-sosudistoi sistem na urovne struktur prodolgovatogop mozga.

The APs of the medulla structures in response to the aorta-vagal stimulation permitted to divide reticular, respiratory and cardiac-vascular "silent" neurons into three groups: those responding to the aorta stimulation, responding to the vagal stimulation, and convergent neurons responding to the aorta-vagal stimulation. The third group neurons seem to maintain an interaction between the respiration and the circulation systems.

[Effect of stimulating the medial and lateral zones of the respiratory center on the electrical activity of the diaphragm, intercostal muscles and phrenic neurons]. / Vliianie razdrazhenii medial'noi i lateral'noi zon dykhatel'nogo tsentra na élektricheskuiu aktivnost' diafragmy, mezhrebernykh myshts i diafragmal'nykh neironov.

Experiments on cats showed that the nucleus of the solitary tract displayed zones whose stimulation provoked separately stimulation or inhibition of the electrical activity of the phrenic neurons and the diaphragm. Stimulation in the nucleus ambiguus of such zones caused stimulation and inhibition of electrical activity of the intercostal inspiratory muscles. In stimulation of the corresponding zone in the giant cell nucleus the electrical activity of both groups of the inspiratory muscles proved to change. It is suggested that the action of stimulation of the giant cell nucleus zones on both groups of inspiratory muscles is mediated through the neurons of the solitary tract and the nucleus ambiguus.
