现代功能成像技术,如正电子发射断层扫描(PET),提供了机会,以检查在一些细节的实施,在人类大脑的心理活动。使用PET获得的局部脑血流量变化的测量值作为局部神经元活动变化的标记,我们检查了单个单词和单词样符号的处理。这些研究揭示了这种实现的分布式,模块化的性质,并提供了一些初步的见解,在这个过程中的记忆机制的作用。
Modern functional imaging techniques such as positron emission tomography (PET) provide the opportunity to examine in some detail the implementation of mental activities in the human brain. Using measurements of changes in local brain blood flow obtained with PET as a marker of changes in local neuronal activity we have examined the processing of single words and word‐like symbols. These studies reveal the very distributed, modular nature of this implementation and provide some preliminary insights into the role of memory mechanisms in the process.
