Effects of High G Forces on the Vestibulo-Ocular Counterroll Reflex of Rhesus Monkeys.
Abstract
A model of the vestibulo-ocular reflex manifest by counterroll was used to determine the effects of high G forces on the response of the vestibular system of rhesus monkeys. Baseline data for determining model parameters were generated prior to subjection to high Gs. After subjecting monkeys to high G, the tests were again run to determine if significant changes had occurred in the model's parameters. The tests consisted of constant speed rotation, pendular oscillations and multiple sine wave oscillations about their line-of-sight. Counterroll was recorded using a linear resolver mechanically fixed to the monkey's eyeball and the data collected analyzed by use of the Fast Fourier transform. The results of this study indicate that the response is not significantly affected by G loading as high as 70G. (Author)
