I don't see how this is a "wow" moment. It is a straightforward consequence of prior materialist commitments, not a discovery of empirical science. If everything is "matter in motion", then ipso facto all mental activity is matter in motion. The problem is that materialism is completely untenable given the way materialism understands matter (e.g., the problem of qualia, the problem of intentionality, etc). Some materialists realize this, but double down and become eliminativists, which is very sad. Also, from what you have said it does not follow that all "mental content" is to be "located" in the brain. That you have brain correlates is not surprising, if only for the fact that without them you would need to wonder what the heck the brain is doing. But you will not find, in the materialist account, a way in which to account for abstraction in the brain. You cannot account for the concept "square" by appealing to the alone (as opposed to say the image of a particular square).
