Your brain is made up of billions of neurons that are constantly firing electrical signals back and forth to tell you what to do, what to think, and how to feel. But your body actually has a second brain that controls you much more than you might realise - and most people have no idea it exists. As this episode of AsapSCIENCE explains, one of the main ways our brain communicates with the rest of our body is via the vagus nerve, which passes messages to the vocal chords, heart, lungs, and the digestive tract. But researchers have also discovered that within the enteric nervous system - the extensive mesh-like network of neurons that controls your digestive tract - the messages are going the other way, too.
