[Effect of narcotic analgesics on impulse conduction along the afferent pathways of visceral nerves].
Experiments were conducted on chloralose-anesthetized cats. The action of morphine and promedol upon the potentials of the cortical and subcortical structures occurring after the visceral nerve stimulation was studied. Morphine proved to depress the potentials evoked by stimulation of the inferior cardiac and vagus nerves, in the specific, associative and nonspecific structures of the brain; promedol produced an analogous effect. Morphine also inhibited the potentials occurring after the stimulation of the splanchnic nerve in the associative and nonspecific structures; depression of the responses in the specific pathways was less pronounced.
