Cerebellar 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...
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 کاملThe vestibulo-ocular reflex: computation in the cerebellar flocculus
The function of the vestibulo-ocular reflex, commonly known as the VOR, is to stabilise an image on the surface of the retina during head movement. One of the parts of the brain involved in this reflex is the flocculus in the cerebellum, which integrates information from multiple sources, including the vestibular apparatus in the labyrinth of the middle ear, motion detectors in visual cortex, a...
متن کاملThe Tangential Nucleus Controls a Gravito-inertial Vestibulo-ocular Reflex
BACKGROUND Although adult vertebrates sense changes in head position by using two classes of accelerometer, at larval stages zebrafish lack functional semicircular canals and rely exclusively on their otolithic organs to transduce vestibular information. RESULTS Despite this limitation, we find that larval zebrafish perform an effective vestibulo-ocular reflex (VOR) that serves to stabilize g...
