You are not your body! We can't be located in the brain, as the body is located in the outer world. Even if you said "I am my brain" you still wouldn't be saying "I'm in my brain." The brain would be in the body, not inside the brain.
And yet, part of us is inside the brain. If you can't take away any part without destroying the whole, it's also sensible to say that we are inside of electrical impulses, as well as being electrical impulses.
We have this annoying habit of dissecting everything into its constituent parts, though.
Matter could very well just be how mind happens to seem, but it gets confusing if you look at it in terms of linear time. Linear time should be thrown out the window, as it isn't really real. The truth is that mind has always existed, and "before" and "after" are ridiculous concepts.
And, as far as dissection goes, and everything's codependency, there's no reason to assume that the entirety of the universe could exist in the absence of any part.
So, in my opinion, we are the body, and every atom of the body...every electron, as well as the action of electrons jumping orbits...and part-in-partial to every last photon of the universe as well.
So, we can't be located, and "YOU" or "ME" is something we cling to out of sheer terror. But matter and time are not as they seem.
The Earth itself (and the Sun) are hurtling through the galaxy. If we could get another perspective of ourselves, all we would see is a blur, like a car going by at 29,000 miles per hour on the highway.
It's been determined that location and velocity can't ever be precisely measured. And what you're really left with is a phantasm. And the truth, as I see it, is that we are spirits living in a spiritual world that becomes mundane to us through familiarity.
There are really limitless directions to travel through time, though, which has dimensions, just as traveling through space is traveling through time.
Nuff said, but, really, as far as scientific understanding goes, I doubt we've scratched the tip of the iceberg.
