在有和没有视觉目标的情况下，对人前庭眼反射的自主控制进行了研究。受试者从0.1-1.0 Hz正弦旋转使用直流眼电描记术记录眼睛的位置。测量前庭眼反射的眼头运动比或增益。当受试者在黑暗中以0.3 Hz的频率旋转，同时进行心算时，增益为0.65。当受试者被要求注视黑暗中静止的假想目标时，增益上升到0.95。当他们想象目标在椅子上与他们一起旋转时，增益下降到0.35。显然，调节前庭眼反射增益的能力并不完全取决于平滑追踪系统。更高的中心必须调节眼速，使其适合于受试者选择的参考系，无论视力是否可用。
Voluntary control of the human vestibulo-ocular reflex with and without visual targets was investigated. Subjects were rotated sinusoidally from 0.1-1.0 Hz using DC electro-oculography to record eye position. The ratio of eye to head movement, or gain, of the vestibulo-ocular reflex was measured. When the subjects were rotated in the dark at 0.3 Hz while performing mental arithmetic the gain was 0.65. When subjects were asked to fixate imaginary targets in the dark that were stationary in space, the gain rose to 0.95. When they imagined targets rotating with them on the chair, the gain dropped to 0.35. Apparently the ability to modulate the gain of the vestibulo-ocular reflex does not depend entirely on the smooth pursuit system. Higher centers must modulate eye velocity so that it is appropriate to the subject''s choice of a frame of reference, whether or not vision is available.
