研究了警觉猕猴的前庭-眼反射（VOR）在水平面上的旋转加速度。使用正弦和伪随机二值序列（PRBS）刺激进行输入输出分析并生成增益和相位参数。在频率范围为0.01-1.28 Hz，刺激幅度范围为16-256/s的正弦研究结果与VOR的线性模型一致。频宽为0.008 ~ 0.45 Hz、振幅为4 ~ 256/s /s的PRBS刺激结果证实了正弦结果。在高旋转频率下获得的正弦数据表明，峰值VOR增益发生在.apprx。4赫兹。正弦和PRBS数据之间的密切一致表明恒河猴的VOR并没有表现出在平稳追求眼运动研究中报道的预测行为。
The vestibulo-ocular reflex (VOR) of the alert rhesus monkey was studied using rotational acceleration in the horizontal plane. Both sinusoidal and pseudorandom binary sequence (PRBS) stimuli were used to perform an input-output analysis and generate gain and phase parameters. Results from sinusoidal studies over the frequency range 0.01-1.28 Hz, with stimulus amplitudes ranging from 16-256/s were consistent with a linear model of the VOR. Results from PRBS stimuli whose bandwidths extended from 0.008-0.45 Hz with amplitudes of 4-256/s per s corroborated the sinusoidal results. Sinusoidal data obtained at high rotational frequencies indicated that a peak VOR gain occurred at .apprx. 4 Hz. Close agreement between sinusoidal and PRBS data suggested that the rhesus VOR does not manifest the predictive behavior reported in studies of smooth pursuit eye movements.
