White Wistar rats were given x-ray doses of 10 r and 25 r on the 18th day of the prenatal development. The rats grown from the litters were subjected to a positive, conditioned reflex to a tone of 400 cycles per second with a 10 decibel attenuation. After obtaining 10 correct positive responses in succession, the rats were subjected to a negative conditioned reflex towards a tone of 800 cycles per second with a 15 decibel attenuation. After five correct negative responses in succession, an attempt was made to obtain 10 correct positive responses in succession to a red bulb of six watts. The responses are typical for each group. After starvation for two days, the intent period of the response decreased in the controls and in the group given a dose of 10 r, but increased slightly in the group given a dose of 25 r. The double conditioned reflex was the most reliable of the tests. It was found that 63.2% of the controls, 12.5% of the rats given a 10 r dose, and none of the rats given a 26 r dose were able to adapt to the double, conditioned reflex within 30 experimental attempts. Both irradiated groups suffer a loss in mobility of higher nervous activity as compared to the control group. (TTT)
