Guys, just because the whole thing of "matter" is at the smallest point a bunch of electromagnetic charges working in certain patterns doesn't mean a whole brain doesn't exist. Sure it can, just not in the form of "stuff" as we know it... rather as a chunk of magnetic charges. It's there, just maybe not in the form that you were familiar with. But that's like nano level garbage that none of us need to really bother with. At our every day level, the idea of the solid matter is a model that works perfectly.
So rest easy.
