[Effect of stimulation of the thalamic reticular nucleus on the neuronal activity of the associative and nonspecific structures of the thalamus].
Neuronal responses in center median, medial dorsal and posterior lateral nuclei to the stimulations of n. reticularis were studied in restrained cats. 53.7, 48.3 and 10%, resp., of the units were affected. Phasing character of "silent" neurons' EPs as well as the responses with primary or secondary inhibitory periods of spontaneously firing units, were demonstrated. A wide variety of the response latencies was revealed in the n. CM (5-33.6 msec; mean: 14.83 +/- 1.7 msec) and the n. DM (3.5-44.8 msec; mean: 18.03 +/- 2.5 msec) neurons. A significant convergence of the n. reticularis and somatovisceral inputs in the neurons of the same nuclei (52.83% and 53.5%, resp.) as well as inhibitory type of interaction between these inputs, were revealed.
