Abstract : A total dose of 100 joules delivered during 1.8 ms at a density of 20 j/sq cm on the midline of the abdomen disrupted performance in the presence of the rewarded stimulus, but did not appear to disorganize the animals; that is, the discrimination between the rewarded stimulus and the nonrewarded stimuli remained intact. The effect disappeared on the third day after irradiation. Lower doses appeared to be ineffective, although differences in individual susceptibility to irradiation preclude a definite finding at this point. A similar dose of 200 joules to the head appeared to be the threshold for performance decrement. There was some evidence that head injury could produce a longer lasting performance decrement and could disorganize behavior in a manner not obtainable with irradiation of the abdomen. (Author)
