title: [Antidromic and synaptic potentials of neurons of the lateral vestibular nucleus of the cat evoked by stimulation of the interstitial nucleus of Cajal and the nucleus of Darkschewitsch].
abstract: Effects of stimulation of the Cajal interstitial nucleus and Darkschewitsch nucleus on the activity of neurons of the lateral vestibular nucleus of Deiters was studied in experiments on cats anesthetized with nembutal. It was shown that stimulation of the mentioned structures lead to antidromic and synaptic activation of Deiters neurons. Ascending axon collaterals of vestibular neurons to the marked brain stem structures were revealed. Stimulation of both Cajal and Darkschewitsch nuclei evoked mono- and polysynaptic EPSP and IPSP in Deiters neurons. The convergence of influences from both nuclei on the investigated neurons was shown. Peculiarities and functional significance of the indicated influences are discussed.
