The vestibulo-auricular reflex.
The mammalian orienting response to sounds consists of a gaze shift that can be a combination of head and eye movements. In animals with mobile pinnae, the ears also move. During head movements, vision is stabilized by compensatory rotations of the eyeball within the head because of the vestibulo-ocular reflex (VOR). While studying the gaze shifts made by cats to sounds, a previously uncharacte...
متن کاملThe vestibulo-ocular reflex of hypergravity rats.
The vertebrate vestibular system detects linear (otolith organs) and angular (semicircular canals) acceleration. The function of the otolith system is twofold, 1: perception of linear acceleration of the head, and 2: assessment of the spatial orientation of the head relative to the vector of gravity. Because of the latter function, a change of gravity will affect the vestibular input which, in ...
متن کاملCortical correlates of vestibulo-ocular reflex modulation: a PET study.
To elucidate cortical correlates of vestibulo-ocular reflex (VOR) modulation, we observed cortical activation during fixation suppression and habituation of caloric vestibular nystagmus in 12 normal subjects, using PET. Significant positive correlation between regional cerebral blood flow (rCBF) and slow phase eye velocity of caloric nystagmus was observed in the middle and posterior insula, in...
متن کاملCerebellar learning in the vestibulo-ocular reflex.
The vestibulo-ocular reflex, because of its close relationship with the cerebellum and its marked adaptiveness, has become a model system for studying the functions of the cerebellum. It has been hypothesized that an evolutionarily old part of the cerebellum, the flocculus, forms a modifiable accessory pathway for the vestibulo-ocular reflex arc for adaptive control, and that the modification i...
متن کاملThe vestibulo-ocular reflex and seasickness susceptibility.
VOR parameters were compared in subjects at the extremes of the seasickness susceptibility scale. Thirty-nine subjects highly susceptible to seasickness and 30 nonsusceptible subjects participated in the study. The VOR was evaluated by the Sinusoidal Harmonic Acceleration (SHA) test at frequencies of 0.01, 0.02, 0.04, 0.08, and 0.16 Hz. In subjects susceptible to seasickness, VOR gain was signi...
