Cardiac interoception,the ability to sense one?s own heartbeat 1, encompasses three critical dimensions:-Interoceptiveaccuracy(behavioral precision in tracking cardiac signals),-Interoceptivelearning(improvement of behavioral accuracy after feedback),-Interoceptive awareness(confidence about one?s own performance).Theserelyondistributednetworkscriticallyengagingtheinsularcortex(IC),theanteriorcingulatecortex(ACC),andthesomatosensorycortex1.Byassessingthesedimensionsintwocontrastivelesionmodels(focalstrokeandearlyneurodegeneration),weaimtorevealcriticallinksbetweenaffectedbrainregionsandspecificaspectsofinteroceptiveperformance
