Dynamic modification of the vestibulo-ocular reflex by the nodulus and uvula

摘要: The time constant of the decay slow-phase eye velocity postrotatory nystagmus or optokinetic after-nystagmus is reduced during exposure to a stationary visual surround (visual suppression). It also after tilting head (tilt A "dump" mechanism in vestibulo-ocular reflex has been proposed rapidly discharge activity from central vestibular system both types suppression. Monkeys lost this lesions nodulus and uvula. They ability habituate on repeated stimuli. Periodic alternating nystagmus, which believed represent an instability reflex, was observed two three monkeys. These data indicate that uvula play important role suppressing, habituating, stabilizing reflex.
