Dynamics and kinematics of the angular vestibulo-ocular reflex in monkey: effects of canal plugging.
Dynamics and kinematics of the angular vestibulo-ocular reflex in monkey: effects of canal plugging. J. Neurophysiol. 80: 3077-3099, 1998. Horizontal and roll components of the angular vestibulo-ocular reflex (aVOR) were elicited by sinusoidal rotation at frequencies from 0.2 Hz (60 degrees/s) to 4.0 Hz ( approximately 6 degrees/s) in cynomolgus monkeys. Animals had both lateral canals plugged ...
متن کاملEffects of Canal Plugging on the Vestibulo-ocular Reflex and 2 Vestibular Nerve Discharge during Passive and Active Head
30 Mechanical occlusion (plugging) of the slender ducts of semicircular canals has been 31 used in the clinic as well as in basic vestibular research. Here, we investigated the effect 32 of canal plugging in two macaque monkeys on the horizontal vestibulo-ocular reflex 33 (VOR) and the responses of vestibular-nerve afferents during passive head rotations. 34 Afferent responses to active head mo...
متن کاملVestibulo-Ocular Reflex Abnormalities in Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo: A Pilot Study
Introduction: Benign paroxysmal positional vertigo (BPPV), involving the semicircular canals, is one of the most common diseases of the inner ear. The video head impulse test (vHIT) is a new test that examines the function of the canals. This study aimed to investigate the vestibulo-ocular reflex (VOR) gain, gain asymmetry and saccades after stimulating all six canals in patients definitively d...
متن کاملCervical nystagmus due to loss of cerebellar inhibition on the cervico-ocular reflex: a case report.
Studies of the cervico-ocular reflex and the vestibulo-ocular reflex have been carried out separately and in combination on a patient with gait ataxia due to a cerebellar tumour. With the head fixed in space, body rotation to the right (left neck torsion) induced marked nystagmus to the left in darkness. Vestibulo-ocular responses to sinusoidal rotation were symmetrical while the neck was immob...
متن کاملCentral versus peripheral origin of vestibuloocular reflex recovery following semicircular canal plugging in rhesus monkeys.
We have previously shown that there is a slowly progressing, frequency-specific recovery of the gain and phase of the horizontal vestibuloocular reflex (VOR) in rhesus monkeys following plugging of the lateral semicircular canals. The adapted VOR response exhibited both dynamic and spatial characteristics that were distinctly different from responses in intact animals. To discriminate between a...
