In fact, the only thing that has ever been observed is some neurons firing off. I have yet to see one shred of evidence that the mind is limited to the brain. It is a totally made up idea. Just because something is happening in the brain doesn't at all mean it is the source. Heck, plenty happens in the spinal cord as well. And plenty happens in my heart. :detective:
Yeah your heart pumps blood
Mental states are in fact starting to be observed in increasing detail:
CMU finds human brains similarly organized
[INDENT]Carnegie Mellon University has taken an important step in mapping thought patterns in the human brain, and the research has produced an amazing insight:
Human brains are similarly organized.
Based on how one person thinks about a hammer, a computer can identify when another person also is thinking about a hammer. It also can differentiate between items in the same category of tools, be it a hammer or screwdriver.[/INDENT] Even as a reckless optimist, I'm frankly astonished that we've already reached this level of detail, and that encoding of concepts is so remarkably similar across brains. You'd think the encoding would be
ad hoc, different for every person, but maybe not quite so much.
There's also a wealth of nitty-gritty detail about sensory input, for example how any given cell in the lowest part of the visual cortex (I'm being a little glib here because the even the sensory cortices aren't
strictly hierarchical) responds only to a very specific visual primitive ... in another case, there was an experiment where some monkeys were conditioned to raise a paw if they saw a certain motion pattern of dots on a screen; the researchers stimulated the cells responsible for picking up on that pattern in another part of the visual cortex (V5) without actually showing it and the monkeys were tricked sure enough.

I didn't insult anyone.
Also the Flying Spaghetti Monster is a parody.
