THE CHANGE IN THE HIGHER NERVOUS ACTIVITY OF MONKEYS DURING RADIATION SICKNESS
Steady conditioned reflexes were developed in monkeys and their higher nervous activity was studied before irradiation. The experiments were performed on 6 hamadryad female monkeys aged 7 to 10 yr. The animals were subjected to single whole-body x-irradiation of 378 r and 399 r, which resulted in phasic disorders in CNS activity, whose severity depended primarily on the typological characteristics of each animal. Thus, the same dose had a different effect on the brain, blood, and cardiovascular system of each animal. During acute radiation sickness, a prolonged suppression of cortical excitability occurred and there were signs of disorders in the main nervous processes. Conditioned reflex activity returned completely one and a half years after irradiation whereas the autonomous activity returned earlier. (P.C.H.)
