Abstract/OtherAbstract:
We study whether stimulation of the vestibular nuclear (VN) complex can modulate rhythmic jaw movements in rats anesthetized by urethane. Rhythmic jaw movements were induced by repetitive electrical stimulation of the orofacial motor cortex. Stimulation of the medial vestibular nucleus (MVN) during the jaw-closing phase increased the amplitude of the jaw-closing movement. (This is not a movement that continues to closure.) Stimulation of the MVN during the jaw-opening phase disturbed the rhythm of jaw movements and induced a small jaw-closing movement. Stimulation of the superior VN (SVN) and the lateral VN (LVN) during the jaw-closing phase did not affect the amplitude of the jaw-closing movement. Stimulation of the SVN and the LVN during the jaw-opening phase increased the amplitude of the jaw-opening movement, however. Stimulation of the inferior VN during the jaw-closing and the jaw-opening phase, respectively decreased the amplitude of the jaw-closing and the jaw-opening movements. Stimulation applied outside the VN did not modulate the amplitude of the jaw movements. These results imply that the VN is involved in the modulation of rhythmic jaw movements induced by stimulation of the orofacial motor cortex.
