Abstract

The behavior of the vestibulo-ocular reflex (VOR) during both passive and active, high-velocity head movements was recorded in three normal subjects. We found that the VOR is compensatory for head velocities up to at least 350 deg . s-1, during both active and passive head rotation provided there is an attempt to visualize a real (or imagined) stationary object in space. Slow phase velocities, however, could reach values as high as 500 deg . s-1. Furthermore, during passive rotation at high velocities, the quick phase trajectory is modified--indicating an interaction between the slow phase and quick phase eye velocity commands.

摘要

在三名正常受试者中记录了前庭眼反射(VOR)在被动和主动高速头部运动期间的行为。我们发现,只要试图在空间中想象一个真实(或想象)的静止物体,在主动和被动头部旋转过程中,VOR对高达至少350度·秒⁻¹的头部速度具有补偿作用。然而,慢相速度可能达到高达500度·秒⁻¹的值。此外,在高速被动旋转期间,快相轨迹会发生改变——这表明慢相和快相眼速度指令之间存在相互作用。
