Characterizing the network supporting interoceptive awareness
The final aim of the study was to characterize an interoceptive attention network supporting adaptive interoceptive sensibility. The rostral ACC was identified as a seed region for psychophysiological interaction (PPI) analysis, convolving the activity in the region implicated as a MAIA covariate with the Active Interoception versus Active Exteroception contrast.Breath interoception led to increased connectivity between the ACC and the frontoparietal dorsal attention network (DAN; The idea of an “always on” interoceptive state is consistent with contemporary theories that place interoception as the background of consciousness, such as Damasio’s “Proto Self” (
