The prefrontal cortex and anterior cingulate cortex are functionally linked as co-activated regions during focused attention meditation [1] and are both integral components of the brain's 'pain matrix' [2]. Furthermore, the anterior cingulate cortex is classified as a subdivision of the prefrontal cortex involved in cognitive control [3], and both regions are implicated in the frontolimbic-parieto-striatal network associated with egoless experiences [4].

referenceA 2016 meta-analysis by Fox et al. of 78 neuroimaging studies found that focused attention meditation produced significant activation in the prefrontal cortex (PFC) and anterior cingulate cortex (ACC), alongside deactivation of the posterior cingulate cortex (PCC) and the posterior inferior parietal lobule.
claimEgoless experiences, measured as 'oceanic boundlessness,' are associated with alterations in the frontolimbic-parieto-striatal network and are positively correlated with cerebral glucose metabolism in Default Mode Network regions (anterior cingulate cortex, hippocampus, inferior parietal cortex) and prefrontal cortex areas (frontomedial superior, frontolateral, and left inferolateral).

referenceSubdivisions of the prefrontal cortex (PFC) implicated in emotion and cognitive control processes, including decision-making, appraisal, and impulse control, include the orbitofrontal cortex (OFC), dorsomedial prefrontal cortex (DMPFC), anterior cingulate cortex (ACC), dorsolateral prefrontal cortex (DLPFC), and ventrolateral prefrontal cortex (VLPFC).
