[Interaction of the visceral and musculocutaneous afferent systems in the secondary somatosensory zone of the cat cerebral cortex].
The convergence of visceral and somatic afferent systems in the secondary somatosensory areas of the cat cortex was studied by means of evoked potentials. The suprathreshold stimulation of the sciatic and brachial plexus nerves depressed the test potentials evoked by the pelvic and mesenteric nerves stimulation. Maximal depression was observed at paired stimulation of visceral nerves. Comparison of the data obtained with mono- and bimodal stimulation suggests that duration of the response restoration period depends on the functional groups of neurons.
