—The effects of space radiation on the central nervous system, which are the most relevant to the assessment of radiation risk in interplanetary flights, can only be addressed in model ground-based experiments on animals. The article substantiates the methodology and presents the results of such experiments: long-term exposure to radiation was simulated using fractionated gamma irradiation of animals...
We studied the effects of irradiation with protons at doses of 1 and 2 Gy in the Bragg Peak with an energy of 170 MeV on learning, recall of skills, and concentration of monoamines and their metabolites in the prefrontal cortex, nucleus accumbens, hypothalamus, striatum, and hippocampus of rats. In the T-maze, we performed discriminant learning with food reinforcement. Rats were trained for 5 days;...
