The paper investigates layer-specific activation in the insula during interoceptive and exteroceptive attention tasks using fMRI and finds increased activity in upper cortical layers during interoceptive attention.

This study investigates how muscarinic acetylcholine and dopamine receptor function affect auditory mismatch negativity (MMN) in schizophrenia, finding differential sensitivity to these neuromodulators.

This study shows that attentional focus modulates the heartbeat evoked potential (HEP), with higher HEP amplitudes during interoceptive attention compared to exteroceptive attention.
