The red regions are the interoceptive sensory regions (dmIns and dpIns).
The blue regions are the visceromotor control regions (rACC, cACC, amygdala, and
vaIns). According to the EPIC model (Barrett
& Simmons, 2015), interoceptive prediction signals travel from
rACC, cACC, amygdala, and vaIns to dmIns and dpIns, and interoceptive prediction
error signals travel the opposite direction. cACC: caudal anterior cingulate
cortex; dmIns: dorsal mid insula; dpIns: dorsal posterior insula; rACC: rostral
anterior cingulate cortex.
