“…, 2017 ). A recent study further showed that compared to the control group, participants primed with MT showed reduced anterior midcingulate cortical activity during the period of feedback showing their loss ( Luo et al. , 2019 ), suggesting that MT could increase individuals’ tolerance to their loss.…”

Awareness of death has been shown to influence human cognition and behavior. Yet, how mortality threat impacts our daily social behavior remains elusive. To address this issue, we developed a dyadic experimental model and recruited 86 adults (43 dyads) to complete two computer-based tasks (i.e., competitive and cooperative button-pressing). We manipulated dyads’ awareness of death (mortality threat vs. neutral control, MT vs. NC) and simultaneously measured their neurophysiological activity using electroencephalography (EEG) during the task. Several fundamental observations were made. First, the MT group showed significantly attenuated competition and slightly promoted cooperation. Second, compared to NC, MT significantly decreased gamma-band inter-brain synchronization (IBS) in the competitive context, which was associated with increased subjective fear of death within dyads. Notably, those effects were context-specific: we did not observe comparable results in the cooperative context. Finally, a machine-learning approach was successfully used to discriminate between the MT and NC groups based on accumulated IBS. Together, these findings indicate that mortality threat to some extent mitigates interpersonal competition, and such mitigation might be associated with changes of gamma-band IBS.

“…Another finding is that MS decreased cingulate and insular activity involved in subsequent reward learning, slowing down brain responses to reward and loss during the learning task. Finally, it was found that stronger functional connectivity between the mid-cingulate cortex and right ventral striatum predicted higher response accuracy in the neutral primed group, but not in the MS primed group, suggesting that mortality salience breaks the link between salience network activity and behaviour (Luo et al, 2019).…”

“…In a fourth study, Han and colleagues studied the effects of mortality salience on functional brain activity involved in a learning task (Luo et al (2019). Participants were again scanned during either MS or negative affect priming, shown a black screen for 7-8 minutes to induce a resting state, and then asked to perform a probabilistic learning task.…”

Thinking about our own death and its salience in relation to decision making has become a fruitful area of multidisciplinary research across the breadth of psychological science. By bringing together experts from philosophy, cognitive and affective neuroscience, clinical and computational psychiatry we have attempted to set out the current state of the art and point to areas of further enquiry. One stimulus for doing this is the need to engage with policy makers who are now having to consider guidelines on suicide and assisted suicide so that they may be aware of their own as well as the wider populations’ cognitive processes when confronted with the ultimate truth of mortality.

“…Previous studies have detected neural activity related to monetary loss. The receipt of monetary loss activates a broad range of brain regions, including the anterior cingulate cortex (ACC), inferior frontal gyrus, medial frontal cortex, insula, cuneus, lingual gyrus, and parahippocampal gyrus (García, Filbey, Dunlop, & Myers, 2013 ; Kocsel et al, 2017 , 2019 ; Lauwereyns, Bjork, Smith, Chen, & Hommer, 2010 ; Luo et al, 2019 ; Ubl et al, 2015 ; Yan et al, 2016 ; Yu, Duan, Wu, & Luo, 2021 ; Yu, Wu, Huang, & Luo, 2020 ). Moreover, a meta‐analysis of monetary loss found that the outcome of monetary loss consistently activated the striatum and anterior cingulate gyri (Dugré, Dumais, Bitar, & Potvin, 2018 ).…”

Both monetary loss and pain have been studied for decades, but evidence supporting the relationship between them is still lacking. We conducted a meta-analysis to explore the overlapping brain regions between monetary loss and pain, including physical pain and social pain. Regardless of the type of pain experienced, activation of the anterior insula was a shared neural representation of monetary loss and pain.The network representation pattern of monetary loss was more similar to that of social pain than that of physical pain. In conclusion, our research provided evidence of the common neural correlates of monetary loss and pain.
