In the experiments on conscious rabbits with the electrodes implanted in the brain it was found by the methods of hydrogen clearance and polarography that piracetam (50 and 500 mg/kg) and phenibut (50 mg/kg) induced a decrease of the local blood flow in the cortex of the frontal, temporal and occipital regions and the total cerebral blood flow. The(More)
Using the hydrogen-clearance method in chronic experiments on alert rabbits, we investigated the dynamics of changes in local and total cerebral blood-flow, oxygen pressure, bioelectrical activity of the motor, auditory, and visual zones of the cerebral cortex, the heart rate during sea-sickness and the effect of the cholinolytic scopolamine upon changes in(More)
In alert rabbits, sea sickness induced an increase in the cerebral blood supply, alteration of the ECoG frequency components, bradycardia, hypotension. Different responses of the bioelectrical activity were revealed in summer and winter. The enhancement of bioelectrical activity and blood flow in the motor cortex were shorter than in the auditory and visual(More)
Sea sickness in alert rabbits induced an increase in the local blood flow in frontal, occipital and temporal cortex as well as an increase of the total blood flow in the brain. The blood flow increases first in the temporal cortex. The changes occur at an unaltered pO2 level in the brain cortex and hypotensive response. The blood flow increase seems to be(More)
It has been established in chronic experiments on intact rabbits by the hydrogen clearance method that stimulation of the vestibular apparatus leads to an appreciable increase in the overall brain blood flow and in the regional blood flow in the frontal, occipital and temporal areas of the brain along with the development of motion sickness.
