Abstract : The action of slow acceleration on experimental dogs under the conditions of cumulation of stimulation resulted in a number of vegetative disorders, similar to the symptoms of sea-sickness. The degree of expression of these reactions was directly dependent on the magnitude of the acceleration at work. Vegetative reactions, observed during the cumulation of stimulation, were manifested in the form of quickening of respiration and pulse fluctuations, a decrease in the amplitude of fluctuations of the curves of pulse and respiration, and increase in salivation, involuntary urination and defecation, general sluggishness, and loss of appetite. The most noticeable changes in the physiological reactions of the organism took place during the action of acceleration frequently changing in magnitude and direction and especially during the action of deceleration. As a result of excluding the function of the vestibular apparatus the normal relations were disturbed between the different analyzers which during the action of acceleration led to an intensification of motor reaction and a disturbance of cortical regulation of the reflex activity of the compensator mechanism.
