General diffuse inhibition of biopotentials was often seen long before the appearance of significant arterial hypotension. The function of the respiratory center was frequently impaired more seriously than that of. the vas'culomotor !center. In ether -ane s thetized cats, the onset of gravitational collapse was considerably faseer. Changes in bioelectric activity appeared at different ,tinies in the various brain centers.' Respiratory excitation was not seen 'in the initial period. Aminazine in a doze sufficient to blockade the reticu. lar formation of the brain stem did not prevent the development of -collapse; the appearance of frequent spikes of high voltage spindle-type trhythms in all leads was characteristic.

It was 'often possible to produce collapse for a second time, in the same animal after a short period, Thus, our investigations demonstrate the existence of regularities in the bioelectric reactions of the brain to changes in the gravitational field vector.
