title: [Electrical responses recorded in the subdiaphragmatic branches of the vagus nerve upon stimulation of a splanchnic nerve].
abstract: Electrical responses of the vagus different branches to a single stimulus applied to the left major splanchnic nerve studied inq--chloralose--treated cats (70 mg/kg). Reflex responses in efferent fibers revealed different conduction velocities: 21.8; 4,5; 1.7 and 0.39 m/sec. The responses persisted after transection of both vagal cervical trunks, spinal cord at the 1st thoracic segment, and after i. v. administration of ganglioblocking agents hexonium or benzohexonium (1--2 mg/kg). The responses disappeared on increase in the stimulation rate to 20/sec and were facilitated after a preliminary series of stimuli. The data obtained suggest that the reflex arch is relayed on the cerebrospinal level and that at least three kinds of preganglionic sympathetic efferent fibers carry reflex firing.
