摘要: Abstract Studies were performed on anesthetized (Dial), paralyzed, vagotomized, artificially ventilated cats. Phrenic efferent activity, ventral respiratory group neuron activity in the region of nucleus retroambigualis and, some instances, thoracic dorsal root compound action potential recorded during electrical stimulation intercostal nerve afferents (INS). and inspiratory (I) neurons inhibited by stimulating external, internal lateral afferents. Some expiratory (E)-neurons also these No I or E-neurons facilitated with INS. Changes E correlated muscle proprioceptor cutaneous receptor afferent fibers. It is concluded that dominant effect abdominal proprioceptive information medullary inhibition activity.
