本文观察了健康受试者闭眼直立时对长时间(10min)静态头转向最大限度适应过程中的前庭运动反应。头部被主动或被动地保持在这个位置。在接受测试的12名受试者中，有5人在适应姿势的过程中感受到了转头角度下降的感觉。对该角度的判断误差可达70-80°。前庭运动对前庭器官电刺激的反应方向也发生了相应的变化。当真实和感知的头部位置冲突时，前庭运动反应的方向因此与空间知觉相匹配，而不是与头部的实际方向相匹配。
Vestibulomotor response during the course of adaptation to prolonged (10 min) static head turning to the furthest limit was investigated in healthy subjects standing upright with the eyes closed. The head was either actively or passively maintained in this position. The sensation of a decline in the angle of head turning was experienced during adaptation to the position by five of the 12 subjects tested. Error in appreciating this angle ranged up to 70–80°. Matching changes occurred in the direction of vestibulomotor response to electrical stimulation of the vestibular apparatus. When true and perceived head position conflict, direction of vestibulomotor response thus matches spatial perception rather than actual orientation of the head.
