title: Caudate nucleus lesions impair the ability of rats to learn a simple straight-alley task.
abstract: Learning to run down a straight alley for a food reward was investigated in rats with lesions of the telencephalon. Over 84 trials the running latencies of rats with lesions of the caudate nucleus were significantly greater than those of subjects with lesions of the frontal cortex or sham-lesioned rats. The running latencies of the cortical- and the sham-lesioned groups were not significantly different. It was suggested that the performance of the caudotomized rats reflected a learning deficit.
