In this episode, Dr. Huberman describes how the body’s organs influence the function and health of our brain and how our brain controls our bodily organs. The conscious awareness of this brain-body dialogue is called interoception. He describes how two factors- mechanical forces (e.g., pressure, pain, volume, etc.) and chemical factors (e.g., gut acidity, microbiome diversity, etc.) combine to influence our moods, control inflammation, immune system, recovery from injury and more. He explains how specific actions of our lungs, heart, spleen, and diaphragm control our brain via the vagus nerve and other neural pathways. Dr. Huberman describes 11 science-supported protocols for enhancing brain-body health and the logic behind them.
