MIT Technology Review Narrated: inside interoception, the hidden sense of how you feel inside

Scientists have a word for how we sense ourselves from the inside: interoception. Today, thanks to a 2021 Nobel Prize and new tools that can map internal signaling across the body, research into interoception is taking off.

As researchers decode how signals move between body and brain, a clearer picture is starting to take shape—with implications for how we treat conditions from obesity to anxiety.
