摘要

Abstract Exteroceptive bodily signals (including tactile, proprioceptive and visual signals) are important information contributing to selfconsciousness. Moreover, prominent theories proposed that visceral signals about internal bodily states are equally or even more important for selfconsciousness. Neuroimaging studies have described several brain regions which process signals related to bodily selfconsciousness (BSC ) based on the integration of exteroceptive signals (e.g. premotor cortex, angular gyrus, supramarginal gyrus and extrastriate body area), and that another brain region, the insula/operculum which is involved in interoception and interoceptive awareness, processes signals critical for selfawareness. Providing evidence for the integration of exteroceptive and interoceptive bodily signals, recent behavioral experiments have demonstrated that the manipulation of interoceptive (e.g. cardiac) signals, coupled with exteroceptive (e.g. visual) signals, also modulatesBSC . Does this integration occur within or outside the structures described above? To this end, we adapted a recently designed protocol that uses cardiovisual stimulation to induce altered states ofBSC tofMRI . Additionally, we measured neural activity in a classical interoceptive task. We found six brain regions (bilateral Rolandic operculum, bilateral supramarginal gyrus, right frontal inferior operculum and left temporal superior gyrus) that were activated differently during the interoception task as opposed to a control task. The brain regions which showed the highest selectivity forBSC based on our cardiovisual manipulation were found in the bilateral Rolandic operculum. Given our findings, we propose that the Rolandic operculum processes integrated exteroceptiveinteroceptive signals that are necessary for interoceptive awareness as well asBSC .
