“…Building upon this knowledge, our finding of a component of interacting networks (DMN, FPN and SN) suggests that the self-related processing requires control of information processing and generating the 'salience map' to motivate the information processing (Shi et al, 2021). This finding is in line with a recently proposed neural model of the self as an object (Sui & Gu, 2017).…”

Resting-state functional magnetic resonance imaging (fMRI) has provided solid evidence that the default mode network (DMN) is implicated in selfreferential processing. The functional connectivity of the DMN has also been observed in tasks where self-referential processing leads to self-prioritization (SPE) in perception and decision-making. However, we are less certain about whether (i) SPE solely depends on the interplay within parts of the DMN or is driven by multiple brain networks and (ii) whether SPE is associated with a unique component of interconnected networks or can be explained by related effects such as emotion prioritization. We addressed these questions by identifying and comparing topological clusters of networks involved in self-and emotion prioritization effects generated in an associative-matching task. Using network-based statistics, we found that SPE controlled by emotion is supported by a unique component of interacting networks, including the medial prefrontal part of the DMN (MPFC), frontoparietal network (FPN) and insular salience network (SN). This component emerged as a result of a focal effect confined to few connections, indicating that interaction between DMN, FPC and SN is critical to cognitive operations for the SPE. This result was validated on a separate data set. In contrast, prioritization of happy emotion was associated with a component formed by interactions between the rostral prefrontal part of SN, posterior parietal part of FPN and the MPFC, whereas sad emotion reveals a cluster of the DMN, dorsal attention network (DAN)

“…In addition to the negative link between self-compassion and the left DLPFC volume, the oppositive direction with that between self-esteem/compassion and the J o u r n a l P r e -p r o o f right DLPFC volume observed in previous studies (Agroskin et al, 2014;Leung et al, 2013) also suggests the hemispheric lateralization of DLPFC (Rêgo et al, 2015;Shi et al, 2021). It has been shown that the left and the right DLPFC have distinct roles in emotion regulation, with the left DLPFC involved in meaning reinterpretation of affective responses and the right DLPFC mediating psychological distancing from affective stimuli (Ochsner et al, 2012;Rêgo et al, 2015).…”

“…One must be generous and generous (or submissive), for both strategies result in less final reward than acting reciprocal. This may explain why regions related to self‐related aspects of experience, including the precuneus, insula, and IPL (Cabanis et al., 2013; Chiao et al., 2009; Harada et al., 2020; Ray et al., 2010; Shi et al., 2021), exhibited negative correlations with the rTPJ.…”

Unselfishness is admired, especially when collaborations between groups of various scales are urgently needed. However, its neural mechanisms remain elusive. In a tri‐MRI dyad‐hyperscanning experiment involving 26 groups, each containing 4 participants as two rotating pairs in a coordination game, we sought to achieve reciprocity, or “winning in turn by the two interacting players,” as the precursor to unselfishness. Due to its critical role in social processing, the right temporal–parietal junction (rTPJ) was the seed for both time domain (connectivity) and frequency domain (i.e., coherence) analyses. For the former, negative connectivity between the rTPJ and the mentalizing network areas (e.g., the right inferior parietal lobule, rIPL) was identified, and such connectivity was further negatively correlated with the individual's final gain, supporting our task design that “rewarded” the reciprocal participants. For the latter, cerebral coherences of the rTPJs emerged between the interacting pairs (i.e., within‐group interacting pairs), and the coupling between the rTPJ and the right superior temporal gyrus (rSTG) between the players who were not interacting with each other (i.e., within‐group noninteracting pairs). These coherences reinforce the hypotheses that the rTPJ–rTPJ coupling tracks the collaboration processes and the rTPJ–rSTG coupling for the emergence of decontextualized shared meaning. Our results underpin two social roles (inferring others’ behavior and interpreting social outcomes) subserved by the rTPJ‐related network and highlight its interaction with other‐self/other‐concerning brain areas in reaching co‐benefits among unselfish players.
