Abstract : Fourteen male monkeys (Macaca mulatta) were trained to perform a visual discrimination task by shock avoidance conditioning. Each animal was exposed to two pulses of radiation separated in time by 6 hours. The total midline tissue dose was approximately 5000 rads. Performance following the second 2500-rad pulse was significantly better than performance following the first pulse. Performance following the second pulse was also significantly better than the performance of a group of animals exposed to a single 4500-rad pulse. Survival time of these two groups was not significantly different. (Author)
