The brain continuously receives, integrates and responds to an influx of sensory signals emerging from the internal organs; this crosstalk is difficult to interrogate causally. In this Review, we discuss developments in multifunctional implantable neurotechnologies aimed at establishing robust bioelectronic interfaces between the brain and the peripheral organs suitable for long-term studies of brain–body signalling.
