The desire to harness electricity for improving human health dates back at least two millennia. As electrical signals form the basis of communication within our nervous system, the ability to monitor, control, and precisely deliver electricity within our bodies holds great promise for treating disease. The nascent field of bioelectronic medicine capitalizes on this approach to improve human health, however, challenges remain in relating electrical nerve activity to physiological function. To overcome these challenges, we need more long-term studies on neural circuits where the nerve activity and physiological output is well-established. In this Letter, I highlight a recent study that takes just such an approach.
