Alterations of characteristics of horizontal gaze fixation reaction in long-term space flights.
The study was performed to explore effects of long-duration SF on the characteristics of horizontal gaze fixation reaction (hGFR). Changes in GFR observed in long-duration space flight (SF) point out to serious disturbances of the VOR system due to, apparently, altered vestibular activity. Two strategies of reaction adaptation to the microgravity conditions were discovered in cosmonauts of civic occupations and pilots.
