02, September, 1998, update.
The "Expedition Number 26", August 13-25, 1998 had the program of investigation being successfully completed.
The medical part of the Expedition had the primary interest in visual system investigation.
This fact is worth to be mentioned as the 1st time in the history of the medical Outer Space research.
The Cosmonaut - Researcher Yury Baturin had performed visual tests every day, except of the 1st day on the Station "Mir". Pre- and after- expedition studies also were done including one right after the landing and during 1 week of adaptation. Visual tests were realized by means of the special PC-notebook program.
"Ocular - complex" is the PC-oriented battery of psychophysical methods, which were designed for the visual system investigation on the different levels of it's organization. It was sent into Outer Space with Cosmonaut - Researcher Y. Baturin being installed on the PC-notebook as well as on the floppy disk as the reserved copy.
"Ocular - complex" realizes the following methods:
Visual Acuity verification in achromatic (standard) and colored tables;
Luminance Sensitivity Threshold (LST) detection in the Central Part of the Visual Field;
Colored combinations of LST studies;
Rhythm's acquisition and reproduction dynamics after the complicated visual stimulation;
"Simple" cognitive functions investigation after the visual stimulation of varied spatial and temporal complexity.
The conditions of the experiments were highly complicated. And it will take a time for the comlete data processing and interpretation.
The preliminary analysis of data demonstrate the following:
the changes in color vision in Outer Space;
pre- and after- expedition cosmonaut's visual system parameters varied in regular way and distinctively through the methods mentioned above;
the adaptation processes in the visual system are believed to have a multystage character;
the LST parameters in colored combinations during the 1st week of adaptation have not been reached the pre-expedition level.
The data are under processing.
The additional information is coming. |
