摘要： 本研究的目的是探讨海马结构(HF)、前额皮层(PFC)和尾-壳核(CP)在大鼠空间认知加工中的作用。实验观察到HP或PFC损毁大鼠Morris迷宫学习或记忆作业成绩显著低于CP损毁组和控制组(CG);HF损毁大鼠主要采用与其它各组不同的“非图类”搜索策略。搜索策略的差异提示:HF和PFC在大鼠图认知加工系统中处于不同的功能层次,HF起相对重要的作用。CP几乎不影响大鼠空间认知能力,表现出哺乳类与鸟类同源结构的功能分化倾向。

Abstract: The effects of hippocampal formation (HF) and prefrontal cortex(PFC)andcaudate-putamen (CP) lesions in rats were investigated in the Morris maze forthe aquisition and retention of spatial cognitive tasks. The results indicate thatboth subjects with HF and PFC lesions lead to spatial cognitive deficits. How-ever, the former usually used paratic strategeies of "no mapping"which weredifferent from the taxic strategies used by the latter. The different strategiessuggest that HF and PFC are in different levels of the spatial cognitive system,the role of HF is more important than that of PFC. The spatial cognitive abi-lity of rats was not affected by CP lesions, which indicates functional differ-entiational tendency. of homology in mammal and birds.
