The mind is the internal holographic representation of perceived internal and external data. Thoughts can extend beyond the confinement of the brain, but all thought is truly imaginary, a brain’s best guess of what data the senses are transmitting and fashioning an “internal picture” of the sensory input.That's a good picture of how I think about what "mind" is. I didn't catch the bad wording on the first read. I auto-corrected in it my head to say "don't neurons extend beyond the brain".
