I’ve just started back into Year 3 of nutritional science and my first module is the Nervous system. Every system I study just blows me away with it’s complexity and how it functions and the nervous system is no different. It is amazing what is going on inside the billions of nerve cells (called neurons) inside our brains and bodies every millisecond of the day. There is no computer or AI in the world that can even come close to performing at the same level as the human nervous system.
