| Abstract |
Susceptibility to motion sickness was studied during exposure to sudden-stop stimulation as a function of gravitoinertial force level. Susceptibility is greatly enhanced, both with eyes closed and eyes open, for zero-g and 2-g conditions in parabolic flight compared with 1-g test conditions. Likely factors are: changes in vestibulo-ocular function, the altered pattern of otolithic activity, and the altered canal-otolith response synergies resulting from exposure to gravitoinertial force levels greater or less than terrestrial levels. These factors are related to the aetiology of space motion sickness. An explanation is proposed for the decrease in susceptibility to motion sickness in Skylab astronauts. |
