Modifications of spontaneous oculomotor activity in microgravitational conditions.
Investigations on spontaneous oculomotor activity were carried out prior to and after (five cosmonauts) and during space flight (two cosmonauts) on the 3rd, 5th and 164th days of the space flight.  Recording of oculomotor activity was carried out by electrooculography on automated data acquisition and processing system "Zora" based on personal computers.  During the space flight and after it all the cosmonauts with the eyes closed or open and dark-goggled showed an essential increase of the movements' amplitude when removing the eyes into the extreme positions especially in a vertical direction, occurrence of correcting saccadic movements (or nystagmus), an increase in time of fixing reactions.
