[The reactions of the viscerosensory neurons of the nucleus solitarius to stimulation of the posterior and anterior hypothalamus].

The "vagal" neurons of the solitary tract nucleus responded to stimulation of anterior and posterior hypothalamus in 78.7 and 27.6 per cent, resp., the responses being mainly of the activation type. The descending effect from the hypothalamus involved primary as well as secondary "vagal" neurons. The responses were of mono-, oligo- and polysynaptic nature.
