I: triple rotary stimulation with undosed; II: single rotary stimulation with undosed; III: single rotary stimulation with saline dosed; IV: single rotary stimulation with anisodamine dosed; V: control group, 4 V: 4th ventricle. Arrows show the CGRP positive cells in the vestibular efferent nucleus.
