Interesting empirical tidbit in this regard -- neurosurgen Frank Vertosik, in his memoirs When The Air Hits Your Brain, speaks of experiments in which most of the brains of housecats were removed, and then the cats returned to their owners. Most of the owners could not tell any difference in the cats' behaviour.
For the nonce, though, this treatment of the mind -- at least as you have described it -- doesn't explain hesitation, confusion, memory, or learning. Is there more to the story?
Yes. Actually nearly everything is as it was. The one major difference is that the free will decides to not do the motion rather than initiating the motion.
