CONCLUSIONS : From the standpoint of vestibular organs, the "basic" 

 susceptibility to motion sickness is lower in weightlessness than under 

 terrestrial conditions. Prevention of motion sickness in any stressful motion 

 environment involves selection, adaptation, and the use of drugs. There 

 appeared to be no inflight inhibitory influences reducing the effective 

 "sensitivity" of the semicircular canals.
