A systematic review and meta‐analysis of memory‐guided attention: Frontal and parietal activation suggests involvement of fronto‐parietal networks.

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.
