기억과 학습에 대한 뇌 매핑

Abstract

Functional magnetic resonance imaging and positron emission tomography studies have identified brain regions associated with different forms of memory and learning. The purpose of this study was to summarize the results of functional neuroimaging studies to construct brain maps for memory and learning. Working memory is associated with the bilateral prefrontal, anterior cingulate, and temporal, and parietal regions ; semantic memory with the left prefrontal and temporal regions ; episodic memory encoding with the left prefrontal and medial temporal regions ; episodic memory retrieval with the right prefrontal, and posterior midline, and medial temporal regions ; skill learning with the motor, parietal, and subcortical regions ; priming with the fusiform and neocortex ; and classical conditioning with the cerebellum. More recent studies have provided higher specificity, by dissociating the neural correlates of different subcomponents of complex memory tasks and the cognitive roles of different subregions of larger brain areas.
