ORIGINAL ARTICLE Multimodal connectivity mapping of the human left anterior and posterior lateral prefrontal cortex

Abstract Working memory is essential for many of our distinctly human abilities, including reasoning, problem solv-ing, and planning.Research spanningmanydecades has helped to refine our understanding of this high-level function as comprising several hierarchically organized components, some which maintain information in the conscious mind, and others which manipulate and reorganize this information in useful ways. In the neocortex, these processes are likely implemented by a distributed frontoparietal network, with more posterior regions serving to maintain volatile information, and more anterior regions subserving the manipulation of this informa-tion. Recent meta-analytic findings have identified the anterior lateral prefrontal cortex, in particular, as being generally en-gaged by working memory tasks, while the posterior lateral prefrontal cortex was more strongly associated with the cog
