| Abstract | intra-subject variability exists within this main sequence ' Saccadic eye movements were studied in six subjects during two Space Shuttle missions. Reaction time, peak velocity and accuracy of horizontal, visually-guided saccades were examined preflight, in flight and postflight. Conventional electro-oculography was used to record eye position, with the subjects responding t o pseudorandomly illuminated targets at 0' and * IO' and 20' visual angles. In all subjects, preflight measurements were within normal limits. Reaction time was significantly increased in flight, while peak velocity was significantly decreased. A tendency toward a greater proportion of hypometric saccades inflight was also noted. Possible explanations for these changes and possible correlations with space motion sickness are discussed. |
