[Convergence and interaction of somatic and visceral inputs in the neurons of the ventral posterolateral nucleus of the thalamus].

Unit activity and field potentials recorded in the cat thalamic VPL nucleus in the radial and splanchnic nerves stimulations, revealed a distinct preference in localization of responses in the mediocentral and centrolateral areas of the nucleus, as well as similarities and differences in the patterns of responses to different types of stimulation. The convergence (particularly during long-latency responses) mostly occurred in the central areas. Inhibitory character of interactions between somato-visceral stimulations was more obvious during conditioned stimulation of the radial nerve.
