And that's exactly why if we drink too much, we end up stumbling and our coordination is not as good as it is when we're sober because alcohol affects the functionality of our cerebellum. Now, what about our myelin cephalon? So the myelin cephalon contains our medulla, also known as the medulla umbilingada. And what Aramidoula actually does is it controls things like breathing, it controls our ventilation rate, our respiratory rate, it controls our heart rate as well as blood pressure and other automatic or involuntary motion. For example, it controls vomiting. So we have the forebrain, we have the mid brain and we have the hind brain.
