SENSORY REACTIONS OF MAN AND SENSITIVITY OF THE VESTIBULAR ANALYZER UNDER SHORT-TERM WEIGHTLESSNESS,
Abstract
Conclusions: The character and degree of manifestation of sensor reactions under short-term weightlessness depend basically on the dissimilar vestibular sensitivity of persons. The results of ground, vestibular testing permit prediction of man's capacity to work in short-term weightlessness. The functional stability of a vestibular analyzer to weightlessness for persons who show no adverse effects (Group I) is determined by a low sensitivity of the vestibular analyzer to an adequate stimulant and by a rather high level of inhibiting effects on the vestibular analyzer as compared to other afferent systems; for persons experiencing illusions in weightlessness (Group 2), by an increased sensitivity of the vestibular analyzer to adequate stimulants and by manifesting the effect of inhibition processes as compared to other analyzers; for persons experiencing motion sickness in weightlessness (Group 3), by a high sensitivity of the vestibular apparatus to adequate stimulants and by a weak inhibition effect of other afferent systems on the vestibular apparatus.
