Working memory is a complex system of cognitive mechanisms for the tempory storage and manipulation of information in our minds. Manipulation here refers to controlled processes operating on the contents of working memory, including selection/inhibition of specific information, attentional shifts between different external or internal demands, or monitoring ongoing events for task-relevant information. Prominent therories postulate that the working memory for verbal information relies primarily on phonological codes. Clinical neuropsychological studies, however, suggest that several distinct linguistic subsystems contribute to verbal working memory: phonological, semantic, and syntactic. In the study of the neural bases of maintenance mechanisms, this refind view of verbal working memory has been largely neglected. In an other domain of language research, however, the distinction between phonology and semantics has been acknowledged and their respresentation in the left inferior prefrontal cortex is investigated using complex language tasks. These different approaches both tax prefrontal working memory processes involved in the controlled guidance of behavior. The present project integrates them with the ideas advanced in the neuropsychological literature on verbal working memory. The longterm goal is to establish a comprehensive model of the neural bases underlying maintance and control processes in the domain of verbal working memory.

工作记忆是一个复杂的认知机制系统，用于暂时存储和处理我们头脑中的信息。操纵是指对工作记忆内容的控制过程，包括对特定信息的选择/抑制，不同外部或内部需求之间的注意转移，或监视正在进行的事件以获得与任务相关的信息。著名的理论认为，言语信息的工作记忆主要依赖于语音代码。然而，临床神经心理学研究表明，几个不同的语言子系统有助于言语工作记忆：语音，语义和句法。在对维持机制的神经基础的研究中，这种对言语工作记忆的重新认识在很大程度上被忽视了。然而，在语言研究的另一个领域，语音学和语义学之间的区别已经得到了承认，它们在左下前额叶皮层的表现是通过复杂的语言任务来研究的。这些不同的方法都税前额叶工作记忆过程中涉及的控制指导的行为。本项目将它们与神经心理学文献中关于言语工作记忆的先进思想相结合。长期的目标是建立一个全面的模型，在言语工作记忆领域的维持和控制过程的神经基础。
