But, is brain the source of consciousness?
It is slightly interesting question. There is unlikely to be too many good outcomes from answers. But it might be something to think about...
You are equivocating here.
It could be a function of both parts. You are equivocating the brain as 1 organ and the brain as 2 organs. If its 2 organs thats doesnt mean a function of the brain has to come from one part or the other.
