# The body sends a signal: Perspectives on interoception

## TL;DR

Scientists are exploring how the brain and body communicate through interoception to improve health.

## Contribution

The paper introduces interoception as a unifying framework for brain–body communication research.

## Key findings

- Four Perspectives illustrate the scope of interoception research.
- Interoceptive pathways may be leveraged to promote health.

## Abstract

Research into brain–body communication is being reinvigorated as the field unites under the umbrella of “interoception.” In this issue of PLOS Biology, four Perspectives show the breadth of this emerging field, highlighting how interoceptive pathways might be used to promote health.

Research into brain–body communication is being reinvigorated as the field unites under the umbrella of ‘interoception’. This Editorial highlights four Perspectives that show the breadth of this emerging field.
