Abstract: In an fMRI experiment, participants were exposed to narratives based on
true stories designed to evoke admiration and compassion in 4 distinct
categories: admiration for virtue (AV), admiration for skill (AS),
compassion for social/psychological pain (CSP), and compassion for
physical pain (CPP). The goal was to test hypotheses about recruitment
of homeostatic, somatosensory, and consciousness-related neural systems
during the processing of pain-related (compassion) and non-pain-related
(admiration) social emotions along 2 dimensions: emotions about other
peoples' social/psychological conditions (AV, CSP) and emotions about
others' physical conditions (AS, CPP). Consistent with theoretical
accounts, the experience of all 4 emotions engaged brain regions
involved in interoceptive representation and homeostatic regulation,
including anterior insula, anterior cingulate, hypothalamus, and
mesencephalon. However, the study also revealed a previously
undescribed pattern within the posteromedial cortices (the ensemble of
precuneus, posterior cingulate cortex, and retrosplenial region), an
intriguing territory currently known for its involvement in the default
mode of brain operation and in self-related/consciousness processes:
emotions pertaining to social/psychological and physical situations
engaged different networks aligned, respectively, with interoceptive
and exteroceptive neural systems. Finally, within the anterior insula,
activity correlated with AV and CSP peaked later and was more sustained
than that associated with CPP. Our findings contribute insights on the
functions of the posteromedial cortices and on the recruitment of the
anterior insula in social emotions concerned with physical versus
psychological pain.
