The results of more than 600 observations of 200 healthy male-volunteers of 23-45 years old including parameters of electroencephalogram, sensorimotor reactions, and questionnaires of Cattell, Strelau and Taylor were analyzed. Division into groups with high, moderate and low vestibuloautonomic resistance (VAR) was done on base of endurance of rotary test with interrupted cumulation of Coriolis accelerations. It is shown, that VAR degree along with distinctions in sensitivity of peripheral compartment of a vestibular analyzer and other sensory systems is appreciably defined by the distinctions in force, lability, activity and dynamism of a nervous system, equilibrium and mobility of processes of excitation-inhibition. VAR is also defined by the distinctions of the initial psychophysiological status characterizing psychomotor reactivity, features of personality, temperament and cognitive abilities, while expressiveness ofvestibuloautonomic disorders in susceptible to motion sickness men is essentially intensified by the influence of their psychoemotional condition during vestibular stimulation-suibjective sensation "lost in space", manifestation of mental discomfort and anxiety, accompanied by autonomic and neurohormonal reactions which extreme form can be characterized as the "syndrome of a threatened state".
