The purpose of the present study was to investigate, by using positron emission tomography, whether the functionally different types of information are subserved by different memory systems in human medial temporal lobe structures. Before explicit retrieval tests during scans, subjects studied words in perceptually and conceptually processed manners separately. It was found that different parts of the medial temporal lobe structures were involved in each of the different conditions. These results indicated that perceptually and conceptually processed types of information were subserved by at least two partially segregated memory systems in human medial temporal lobe structures.
本研究的目的是通过正电子发射断层扫描来探究人类内侧颞叶结构中不同功能类型的信息是否由不同的记忆系统提供支持。在扫描期间进行明确的检索测试之前，受试者分别以感知和概念处理的方式学习单词。结果发现，内侧颞叶结构的不同部分参与了每种不同的条件。这些结果表明，在人类内侧颞叶结构中，感知和概念处理类型的信息至少由两个部分分离的记忆系统提供支持。
