Prior knowledge and long‐term memory can guide our attention to facilitate search for and detection of subtle targets embedded in a complex scene. A number of neuropsychological and experimental studies have investigated this effect, yet results in the field remain mixed, as there is a lack of consensus regarding the neural correlates thought to support memory‐guided attention. The purpose of this systematic review and meta‐analysis was to identify a common set of brain structures involved in memory‐guided attention. Statistical analyses were computed on functional magnetic resonance imaging (fMRI) studies that presented participants with a task that required them to detect a target or a change embedded in repeated and novel complex visual displays. After a systematic search, 10 fMRI studies met the selection criteria and were included in the analysis. The results yielded four significant clusters. Activity in right inferior parietal (Brodmann area [BA] 9) and right superior parietal (BA 7) lobes suggests involvement of a fronto‐parietal attention network, while activity in left mid‐cingulate cortex (BA 23) and right middle frontal gyrus (BA 10) suggests involvement of a fronto‐parietal control network. These findings are consistent with the notion that fronto‐parietal circuits are important for interfacing retrieved memories with attentional systems to guide search.

记忆引导注意的系统评价和荟萃分析:额叶和顶叶激活表明额顶叶网络的参与

先验知识和长期记忆可以引导我们的注意力,以促进对嵌入在复杂场景中的微妙目标的搜索和检测。许多神经心理学和实验研究已经调查了这种影响,但该领域的结果仍然喜忧参半,因为对于被认为支持记忆引导注意力的神经相关性缺乏共识。本系统评价和荟萃分析的目的是确定一组与记忆引导注意有关的常见大脑结构。对功能性磁共振成像 (fMRI) 研究进行了统计分析,该研究向参与者提出了一项任务,要求他们检测目标或嵌入重复和新颖的复杂视觉显示中的变化。经过系统的搜索,10 项 fMRI 研究符合选择标准并被纳入分析。结果产生了四个重要的集群。右下顶叶(布罗德曼区 [BA] 9)和右上顶叶(BA 7)的活动表明额顶叶受累注意网络,而左侧中扣带回皮层(BA 23)和右侧额中回(BA 10)的活动表明参与了额顶叶控制网络。这些发现与额顶叶回路对于将检索到的记忆与注意力系统连接以指导搜索很重要的观点是一致的。
