Rachel Feltman: For Scientific American’s Science Quickly, I’m Rachel Feltman. People often talk about having “gut feelings,” but new research suggests there may be more to the idiom than we thought. Scientists are finding that specialized cells in our intestines can send signals directly to the brain, potentially influencing appetite and even mood. Recent studies hint that our microbiomes could play a role in this communication system, though researchers are still trying to understand exactly how these interactions work and what they mean for our health. Here to walk us through the emerging science of the belly-to-brain connection is Maya Kaelberer, an assistant professor at the University of Arizona in the Department of Physiology.
