The results of studying the vestibular function and the function of spatial perception in 26 cosmonauts before and after 30 space flights are discussed. The typical postflight changes in these functions were: an increase in the reactivity of the otolith organ, a decrease in the sensitivity of semicircular canals, a decline in the accuracy of perception of spatial coordinates, asymmetry of most parameters, development of illusionary reactions inflight. The cosmonauts also showed individual variations with respect to the degrees of the above responses, the dynamics and length of adaptation, the development of the motion sickness symptom-complex, etc. At R+O some cosmonauts exhibited a change in the direction of the eye counter-rotation, i. e., the negative otolith reflex or at turn towards the tilt direction. Possible mechanisms of these vestibular changes are discussed.
讨论了对26名宇航员在30次太空飞行前后前庭功能和空间感知功能的研究结果。这些功能典型的飞行后变化为：耳石器官反应性增加、半规管敏感性降低、空间坐标感知准确性下降、大多数参数不对称、飞行中出现虚幻反应。宇航员在上述反应程度、适应动态和时长、晕动症状复合体发展等方面也表现出个体差异。在R+O时，一些宇航员出现眼反向旋转方向的变化，即负耳石反射或转向倾斜方向。讨论了这些前庭变化的可能机制。
