If we imagine there's a God and I could ask any 1 question about the brain and get an anaswer, all I would need to ask is:
"Hey God: w.r.t. the human brain, are there any special shenanigans like is connected to a soul that's responsible for consciousness, or is it WYSIWYG, just a bunch of cells and that's it?"
Luckily for you, there is no God and I can answer definitively: no, there are no shenanigans. It's just some cells and that's it. I am telling you this definitively. There are no metaphysical shenanigans going on in the human brain.
Note: you might wonder why, for this answer, I decided to phrase it in terms of asking God. The answer is in order to activate the natural scientist's reaction "that's silly, God can't tell you there's no God like that". Well, brain metaphysics is exactly and equally silly. It's just some cells, that's all.
