Hi @Sehnsucht and @Former-Member,
in all the reading I've done over the years about the human brain and from all the documentaries I've watched about neuroscience, I never did get the impression that our brains were much like computers.
I only know that research on the brain is still in it's infancy and many theories we once held are now in serious question.
I just thought that calling the brain 'the computer' of the body was an easy way to explain it's function to children! Seriously, that's as far as I thought the comparison went. 
Even though my own brain is seriously dysfunctional, I still marvel at it's abilities. I think the ability we have to feel emotion, compassion and to be creative and feel awe is what makes us human. Creativity, in particular, is something a computer will never have any use for. (Of course I realize that computers can be programmed to generate what we might label random "creative" images, but the computer can't make any decisions about what looks good, when deciding among these images. They are a meaningless novelty.)
This is off the topic, but I always laugh when people say "computers might one day take over the world". Because a computer has no will- it doesn't desire power. A computer is inert; lifeless. It has no motivation to take over the world. It doesn't even have the concept of what the world is. It can't even conceive of it's own existence, anymore than what a vacuum cleaner can!
