Interoception: How Your Brain Builds a Sense of Self Out of Vagal Signals
Your sense of being you — grounded, present, alive in a body — is not a fixed fact. It is assembled, moment by moment, from a stream of signals rising from your organs. A region of cortex reads your heartbeat, breath, and gut and builds a felt self out of them. When that reading goes wrong, so does the self it produces.
