Central 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...
متن کاملSemicircular canal plugging shifts the frequency of spatial-temporal convergence (STC) in central vestibular neurons.
INTRODUCTION Oscillating the head about a spatial horizontal axis activates both the vertical semicircular canals (VC) and the otolith organs. It is generally assumed that in-phase modulation of unit firing rate (FR) with head position indicates convergent otolith input, while in-phase modulation with head velocity indicates VC input. The amplitude of FR modulation depends on head orientation i...
متن کاملDynamics 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 کاملRound window plugging in the treatment of superior semicircular canal dehiscence.
OBJECTIVES/HYPOTHESIS Objectives were to describe the use of round window plugging for superior semicircular canal dehiscence syndrome and review further recommendations regarding the procedure based on our experience and to compare results with recent literature on round window plugging. STUDY DESIGN Retrospective case series. METHODS Fourteen patients underwent round window plugging for s...
متن کاملSpatial orientation of caloric nystagmus in semicircular canal-plugged monkeys.
We studied caloric nystagmus before and after plugging all six semicircular canals to determine whether velocity storage contributed to the spatial orientation of caloric nystagmus. Monkeys were stimulated unilaterally with cold ( approximately 20 degrees C) water while upright, supine, prone, right-side down, and left-side down. The decline in the slow phase velocity vector was determined over...
