[Neuronal organization of the somatovisceral afferent systems of the centromedian area of the thalamus].

High responsiveness of the center median neurons to stimulation of radial, sciatic and splanchnic nerves was found in unterstrained cats. The mean latencies of the responses were 24.1 ms, 28.4 ms and 38.4 ms, resp. A considerable convergence (up to 82%) was revealed. The inhibitory type of interrelationships prevailed among the afferents under study, being more obvious during the somatic stimulations. Theoretical aspects of these and other findings are discussed from the standpoint of the thalamic unspecific level of the somato-visceral integration mechanisms.
