title: [Disorders in rat's higher nervous activity in the course of chronic gamma-irradiation].
abstract: Investigations of early disorders in rat's higher nervous activity in the course of chronic gamma-irradiation (elaboration of the conditioned defensive reflex of avoidance "under the ray") showed that already in 10-15 minutes since the beginning of exposure (total dose of approx. 0.75-1.15 Gy) the conditioned reflex parameters degraded significantly with a general trend toward an increased excitation and disruption of active inhibition in the higher sections of the central nervous system (CNS). The most dramatic disorders occurred in the middle of the period of exposure (total dose of approx. 4-5 Gy). There were some individual differences in the CNS functional reaction to irradiation.
