The influence of learning ability of irradiated and intact rats-parents on higher brain function of their offspring

Abstract

The ability to train the offspring of male rats irradiated at a dose of 0.5 Gy was studied. Cognitive (memorable) brain functions were evaluated by their ability to develop and reproduce a conditioned reflex of active avoidance. It is established that the initial state of cognitive functions of the brain of parents affects the development of these functions in the offspring. Taking into account this factor will allow to avoid methodological errors, consisting in the random formation of groups, unequal in the initial psychophysiological parameters. The expediency of such a previously not used approach is demonstrated on the model of irradiation in a small dose (0.5 Gy) of male germ cells. It is established that the intensity of the radiation effect on this criterion can vary significantly with different approaches to the formation of groups of parents.
