Stimming behaviours can consist of tactile, visual, auditory, olfactory and vestibular stimming. Gentamicin should be used cautiously in persons with renal, auditory, vestibular, or neuromuscular dysfunction. The vestibulocochlear nerve has two components, the auditory and vestibular portions. Stereocilia exist in the auditory and vestibular systems. Height vertigo is caused by a conflict between vision, vestibular and somatosensory senses. If the proprioceptive and vestibular pathways are intact, balance will be maintained. Neurons of the adjacent vestibular ganglia monitor the hair cells in these ducts. Nystagmus and oscillopsia are two conditions that overlap the vestibular and ocular systems. Derealization can possibly manifest as an indirect result of certain vestibular disorders such as labyrinthitis. The treatment for vestibular neuritis depends on the cause. Norepinephrine modulates the intensity of central reactions to vestibular stimulation and facilitates compensation. About half report vestibular (vertigo) problems. Vertigo typically indicates a problem in a part of the vestibular system. The neuromotor manifestation of the fencing response resembles reflexes initiated by vestibular stimuli. The laryngeal cavity above the vestibular folds is called the vestibule.
