[The effect of a high-intensity radiation exposure on the brain function of monkeys. The postradiation changes in brain bioelectrical activity].

: In experiments with Macaca fascicularis it has been found that changes in the total bioelectric activity of the brain within the EEG range that occur during the first 60 min following whole-body irradiation with a dose of 45 Gy (6.5 Gy/s) are interrelated with the dynamics of nervous and psychic activity of the exposed animals, exhibit a definite stereotype of their development (disorganization of rhythms: generalized synchronization of biopotentials; and development of synchronous processes), and coincide in time with the main stages of the development of the clinical picture of the acute postirradiation period (noncoordinated stimulation, sopor or coma, and partial recovery).
