claimKilpatrick et al. (2011) found increased functional connectivity between areas implicated in present-centered episodic awareness, such as the dorsomedial prefrontal cortex (DMPFC), and sensory areas, such as the primary somatosensory cortex (SI) and secondary somatosensory cortex (SII).
measurementDispositional mindfulness, assessed by the Kentucky Inventory of Mindfulness Skills (KIMS), positively correlates with bilateral activation of the dorsomedial prefrontal cortex (DMPFC) during the reappraisal of negative pictures, according to Modinos et al. (2010).
claimSamatha-vipassana practitioners with 5,000 to over 10,000 hours of practice demonstrate increased BOLD activation in the rostral anterior cingulate cortex (ACC) and dorsomedial prefrontal cortex (DMPFC) during focused attention (FA) meditation, according to studies by Holzel et al. (2007) and Manna et al. (2010).
referenceThe fronto-parietal control system (FPCS) consists of the rostral frontopolar prefrontal cortex (FPC), right ventrolateral prefrontal cortex (VLPFC), dorsomedial prefrontal cortex (DMPFC), dorsal anterior cingulate cortex (ACC), dorsolateral prefrontal cortex (DLPFC), anterior insular cortex (AIC), lateral cerebellum, and anterior inferior parietal lobe (aIPL).
measurementFarb et al. (2012) observed that connectivity between the dorsomedial prefrontal cortex (DMPFC) and the insula was absent during exteroceptive focus.
claimBrain areas involved in mentalizing include the temporoparietal junction (TPJ), temporal pole (TP), anterior insular cortex (AIC), precuneus, and dorsomedial prefrontal cortex (DMPFC).
measurementTaylor et al. (2012) found that adept Zen meditators exhibit stronger connectivity between the dorsomedial prefrontal cortex (DMPFC) and the inferior parietal lobule (IPL) compared to novices.
measurementFarb et al. (2012) found that the dorsomedial prefrontal cortex (DMPFC) is deactivated and negatively coupled to the posterior insular cortex (PIC) during interoceptive awareness.
referenceThe dorsomedial prefrontal cortex (DMPFC) and dorsal anterior cingulate cortex (ACC) modulate the physiological and behavioral expression of fear and are critical in extinction and reconsolidation, as reported by Quirk et al. (2010).
measurementHolzel et al. (2007) showed strong activity in both the dorsal anterior cingulate cortex (dACC) and the dorsomedial prefrontal cortex (DMPFC) during specific tasks.
claimThe dorsomedial prefrontal cortex (DMPFC) may act to integrate narrative and experiential information, sustain positive activation in interoceptive areas, or decouple from them without suppression.
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).
claimAndrews-Hanna et al. (2010) demonstrated that a first-person perspective (FPP) episodic judgment task concerning one's present situation activates the dorsomedial prefrontal cortex (DMPFC) subsystem, which includes the temporoparietal junction (TPJ), lateral temporal cortex (LTC), and temporal pole (TP).
claimThe Frontoparietal Control System (FPCS) has functional overlap with the Experiential Self-specifying (EPS) network, which includes the dorsolateral prefrontal cortex (DLPFC), dorsomedial prefrontal cortex (DMPFC), and anterior insular cortex (AIC).
claimInteroceptive awareness in individuals trained in Mindfulness-Based Stress Reduction (MBSR) recruits decreased dorsomedial prefrontal cortex (DMPFC) activity and negative functional connectivity with the posterior insular cortex (PIC), suggesting a role for the DMPFC in modulating primary interoceptive areas, according to Farb et al. (2012).

referenceThe major subdivisions of the Default Mode Network include the ventral medial and dorsal medial regions of the prefrontal cortex, the posterior cingulate cortex (PCC) with the precuneus, and the lateral parietal cortex.
