This work was conducted on white rats. On the 12th day of pregnancy the animals were subjected to a total single irradiation (200 r) by γ-rays of radioactive cobalt. The study of the highest nervous activity of rats irradiated during the anternatal period reveals a congenital decrease of the working capacity of their cortical cells as compared to the normal animals. Both fundamental nervous functions are not as strong in the animals irradiated antenatally. These processes are less mobile and less interbalanced. The processes of internal inhibition, especially of extinction and differentiation, are particularly affected.
