Some visual, vestibular and proprioceptive reflexes which contribute to gaze (head + eye) stabilization were quantified in the chameleon. All the reflexes were analysed in the horizontal plane, and the visual reflexes were also studied in the vertical plane. In restrained-head animals, both the optokinetic nystagmus (OKN) and the vestibulo-ocular reflex (VOR) had low gains. In free-head animals, the head (opto-collic or vestibulo-collic reflex) and eye (OKN or VOR) responses added their effects, thus improving gaze stabilization, especially during vestibular stimulation. Cervical stimulation provoked both a cervico-ocular reflex (COR) in the compensatory direction and a large number of saccades. The saccadic response was especially marked in the presence of patterned visual surroundings.
在变色龙中，对一些有助于注视（头部+眼睛）稳定的视觉、前庭和本体感受反射进行了量化。所有反射均在水平面进行分析，视觉反射也在垂直面进行了研究。在头部受限的动物中，视动性眼震（OKN）和前庭眼反射（VOR）的增益都较低。在头部自由的动物中，头部（视-脑桥或前庭-脑桥反射）和眼睛（OKN或VOR）的反应叠加其效应，从而改善注视稳定，尤其是在前庭刺激期间。颈部刺激引发了补偿方向的颈眼反射（COR）以及大量的扫视。在有图案的视觉环境中，扫视反应尤为明显。
