Dr. Todd Coleman, an associate professor of bioengineering at Stanford University, explores the profound and literal connection between the stomach and the brain, often referred to as the body's "second brain" due to the approximately 300 million neurons in the GI tract. 

Dr. Coleman explains that "gut feelings" are scientifically grounded in the concept of interosception—the sense of the body's internal state—which modulates cognition and decision-making. His research uses the electrogastrogram (EGG) to measure the stomach's electrical activity, revealing a crucial dialogue with the brain during non-REM sleep.
