[The electrical activity of the monkey brain in the period of early transient incapacity during gamma-irradiation at high dose rates].

Changes in the electroencephalogram (EEG) of Macaca fascicularis during early transient incapacitation (ETI) were shown to correlate with the dynamics of clinical manifestations of the damage. Irradiation caused desynchronization of EEG followed by a generalized retardation of its fluctuations reaching the maximum at the height of ETI. EEG disturbances in animals during the comatose phase of ETI indicated a severe inhibition of the brain cortex functional activity.
