Abstract

I propose working memory be considered, not as a process for static maintenance in a particular set of brain regions, but rather as a dynamic process unfolding to serve future needs. Brain regions such as the hippocampus, or sensory and motor regions, may be necessarily recruited during this process, depending on task demands. Information stored in working memory is thus a distributed representation reflected in the structural and functional state of multiple brain areas and the trajectory of that state over time. Recent research is discussed in support of this view.

摘要

我提出将工作记忆视为一种动态的过程,而不是在特定的脑区中对特定的信息进行静态保持的过程,这种动态过程的展开是为了满足未来的需求。在这个过程中,根据任务的需求,可能需要调用大脑中的海马体或感觉运动区域等脑区。因此,工作记忆中存储的信息是一种分布式的表示,反映了多个脑区的结构和功能状态以及该状态随时间的变化轨迹。本文将讨论最近的研究来支持这一观点。
