[Effect of vestibular, somatic and autonomic afferent impulsation on the activity of individual neurons in the nuclei of the cat vestibular complex].
Responses of single vestibular neurons were studied in cats under adequate and electric stimulation of different afferent sources (labyrinths, mixed nerves, n. vagus, n. depressor, limb movements). Different types of responses to the employed stimulation as well as evoked activity as bursts followed by depression of background firing are described. The activity of vestibular neurons is shown to depend on extralabyrinthal stimulation. The role of muscle-joint receptors is distinguished from natural stimulation of the vestibular apparatus during the head tilting. Somatotopic organization of vestibular nuclei and convergence of different afferental impulses to the neurons forming the vestibulospinal tract are discussed.
