Abstract
SummaryOffspring of non-irradiated rats which received a single dose of 150 r x-irradiation on 10th, 14th or 18th day of pregnancy respectively or 300 r on 18th day of pregnancy were exposed at approximately 6 months of age to a brightness discrimination problem. Data were evaluated on the basis of number of trials to criterion and number of errors for the various groups on the day when offspring of non-irradiated group reached criterion. Findings indicate that a single exposure of 150 r on 14th day or 300 r on 18th day of pregnancy significantly impaired discrimination learning performance as compared to the performance of non-irradiated rats or offspring of rats administered a single dose of 150 r x-irradiation on 10th or 18th day of pregnancy.
