I want to say a bit of both, but I can't imagine how far away we are. The mind carries one of the most advanced file storage and retrieval systems, and on top of that, it's not like one activity happens only in one place. The mind works with several other parts in conjunction with most common tasks (blood flow increases in many parts of the brain when you look at a picture, triggering a lot of different things to happen at once). Just knowing that blood flow increases is only a measure of the energy used, it doesn't even tell us what's happening at the lowest level. Correct me if I'm wrong, I'm always very interested in this sort of stuff. I've been given a few book recommendations which I hope to take time to get around to, just swamped with work and have a few books on my list already.
