Neurobiological effects due to intrauterine exposure of rats with 131I

The article studies the influence of prenatal exposure of rats with 131I on their behavioral activity and anxiety using the open field test, an elevated raised cross-shaped maze, black and white and shuttle box. It is determined that prenatal exposure of rats with 131I has led to increased research activity, but did not cause significant changes in the levels of animals’ anxiety. There has been also an decrease in the number of conditioned reflexes and prolongation of the latent periods of reflex reactions, indicating that there is some suppression of CNS due to exposure conditions
