the "two brains" theory

The "two brains" theory suggests that our body operates with two interconnected yet distinct centers of control: the brain in our head and a complex nerve network called the enteric nervous system in our gut. While the brain in our head handles conscious thoughts and decision-making, the gut's nervous system manages digestion and sends signals about our emotional state, often influencing mood and stress levels. This bi-directional communication explains how feelings like nervousness or happiness can be experienced physically, highlighting a close link between our mental state and gut health.
