Figure 1. A schematic of the interoceptive network.

Figure 1.

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.
