Influence of the hypothalamic stimulation of vestibular nuclei units in the rat.
Electrical stimulation of rat hypothalamus influenced the activity of the vestibular nuclei units, depending on the stimulus location. Vestibular units were excited predominantly by antero-lateral hypothalamic stimulation, whilst middle-medial hypothalamic stimulation mainly induced a decrease in the firing frequency of vestibular units. The possibility of both types of hypothalamic influence on vestibular excitability is discussed.
