The effect of x rays was studied on the development of the brain of white rats in the enrly postnatal period (from birth to 14 days). This period was chosen because active processes of growth and multiplication of cells and capillaries and formation of various portions of the brain take place in rats during the first 14 to 17 days. After irradiation the disturbance of the growth of the cerebral hemispheres is manifested in decrease of their size, especially of the medial portion of the occipital lobe. The injurious efiect of x rays is especially pronounced in the cerebellum. However, there is no disturbance in the growth of corpora quadrigemina. The weight of the rat's brain irradiated on the 1 to 14th day of life is much less than in the control animals. The earlier the irradiation the greater its injurious effect on the brain development (the dose being the same). (tr-auth)
