The effect of increased nitrogen pressure on motor activity and the intercentral relationships of the brain of monkeys

The influence of increased nitrogen pressure up to 19 ata was investigated in chronic experiments on monkeys of a species of Javan macaques (Macaca irus)with electrodes implanted in cortical and subcortical regions of the brain. The phasic character of the changes of motor activity of the animals, an increase in the spectral density of the average power of the EEG in the range of frequencies from 4 to 20 Hz, and a disturbance in the connectedness of the electrogenesis of the reticular formation of the midbrain with the bioelectrical processes in the substantia nigra, the head of the caudate nucleus, and the frontal and motoric areas of the cortex were identified in the course of nitrogen compression at a rate of 1.0 ata per 1 min.Translated from Fiziologicheskii Zhurnal imeni I.
