No, it doesn't.
Even if we reject religion, and, say, go for a "World is actually The Matrix" hypothesis (which, similarly, has human bodies controlled by observers external to the observed world", the best we can genuinely say about this region of the brain is that activating it disables "whatever controls the brain" (internal or external.) Unless the observers have an seperate memory (and why would they?), everything is consistent with that observation link being severed. The observers (be they souls or Matrix hook-ups) are no longer able to modify the brain's memory, to move the body, or in any other way interact with it. When that part of the brain is allowed to operate again, they can do so.
If we at least assume memory is local, which it has to be, there's no incompatability. If memory is not local, it's still possible there's no incompatability because the lack of communications between observer and avatar will result in no memory data being written.
On the other hand, the good news is that as you haven't proven the non-existence of God, you will be unable to prove that black is white, and thus will not be killed on the next Zebra crossing.
