Physio psychological study on the role of caudate nucleus in spatial memory in rats.

本实验观察了损毁尾状核对大鼠空间记忆任务的影响。结果表明，尾状核前背侧核损伤会影响在丰富线索条件下的径向迷宫行为，并影响延迟眼匹配任务的选择准确性，但不影响自我中心反应学习和分配空间任务的获得，尾状核后侧核损伤会影响自我中心反应学习，但不影响延迟眼匹配任务的获得，结论尾状核前背侧核在空间工作记忆中具有重要作用。

The effcs of caudate lesions on spatial memory tasks were examined in rats. As the results, damage to the antero-dorsal caudate nucleus impairs the radial maze performance in the enriched cue conditions, and the choice accurac y of the deleyedmatching to sample task.It does not impairs aquisitions of egocentric response learning nor allocent ric spatial task.On the contrast,damage to the posterior caudate nucleus impairs egocentric response learning but not deleyedmatching to sample task,nor allocentric spatial task.It was concluded that antero-dorsal caudate nucleus has some important role in spatial working memory.
