Abstract

The purpose of this study was to investigate the effects of dorsomedial thalamic nuclei lesions on cognitive learning task(eq. maze learning) and emotional learning task(eq. conditional avoidance learning) in the rat. The results of this study were as follows. First, experimental group showed significantly more errors than control group in the Hebb-Williams maze task, Second, experimental group showed significantly lower learning ability than control group in the one-way conditional avoidance learning. Third, in the maze learning, experimental group showed reduced errors in the second day learning compared to the first day learning score. But, in the conditional avoidance learning, does not showed any difference between two days learning score. These results suggested that dorsomedial thalamic nuclei might be related to emotional learning task, as well as cognitive learning task.
