Vertical vection is a phenomenon of self-motion perception in immobile subjects, which is conventionally perceived in the opposite direction of the upward or downward moving visual stimulus. The Austrian scientific cosmonaut experienced reversed vertical vection from sinusoidal stimulation on third and sixth day of space flight as well as immediately postflight. The occurrence of short periods of reversed vection from constant velocity stimulation six months postflight can be interpreted as a reactivation of an "alternative" visual processing mode. This may indicate that microgravity modulations of the neuronal pathways which process visual information for dynamic orientation are not completely extinguished in the processes involved in readaptation to 1-G.
垂直运动错觉是静止不动的受试者产生自我运动感知的一种现象，传统上这种现象是在视觉刺激向上或向下移动的相反方向被感知到的。这位奥地利科学宇航员在太空飞行的第三天和第六天以及飞行后即刻，因正弦刺激而经历了反向垂直运动错觉。飞行后六个月因匀速刺激出现的短时间反向运动错觉，可被解释为一种“替代性”视觉处理模式的重新激活。这可能表明，在重新适应1-G的过程中，处理动态定向视觉信息的神经通路的微重力调制并未完全消失。
