Jay is here, but about to go to sleep. Jay anticipates reading more later and would greatly appreciate any interesting thoughts. You all are encouraged to start PM correspondences so as to avoid these unsightly lumps of quoted stuff when Jay catches up on lost time.
As forumrunner said, computing processes are based on sequential logic. The brain, being an organ, is based on chemical reactions and impulses. They are, in operation, more or less polar opposites.Uh... That was tortuous. A PC's functioning is based on sequential logic, with electric potential driving change. A brain's functioning is based on parallel processes intersecting, converging, diverging, starting and terminating all over the place, with chemical potential driving change. A brain's logic matrix is at least three-dimensional, (if not more, with all of its twisted connections) so even more complex rythms and interference patterns can also develop. Those might also have some role in thought, emotion, memory, whatever...

"It is not known how the human brain store information. But if you presume that it is stored in a way that is similiar to computers, that, for example, each contact between the neurons can be either 'on' or 'off', a therefore store a piece of information, the human brain can store up to 12 000 GB"Neurons have many more logic states than just on and off. They have analog states associated with each of a whole buttload of different neurotransmitters.
Maj. Pain:
Humans have yet to nake a self dterminating learing capable program(esentially an A.I.)
so for now its a program mimcking thoughts. for now.Jay wants to point out a difference between the computer programs humans have made and the complex patterns emerging in our brains. The attempts Jay has heard about to create some form of AI involved writing some program directly. The patters of our minds (all natural intelligence?) weren't written directly by a programmer. They were allowed to emerge from stimulus-response reactions between innumerable neurons connected in fantastically complex ways.
zoggyzoggerson:
I read an article a while back (sorry can't remember where) that was about a program written that would take anything (say a computer chip) and improve on it by comming up with 3 different designs and testing and picking the best ones... well anyways when it was done with the circut board they gave it they technicians couldn't figure out what it did to it, because it looked like it had unneeded components and such but when they removed one the looked like it had no purpose the whole thing stopped working... anyhow what I'm getting at is they think if they set this program to work improving its self that it might come up with artificial intelligence.That sounds exactly like something Jay read about more than a year ago, except that it wasn't just a program. It was an entirely different kind of computer chip (NOT CIRCUIT BOARD, BLAMNIT!) whose configuration of connections between logic gates could be changed. It wan't making new circuits out of new material, just reconfiguring the same chip. Major Pain needs pay more attention, Zoggy never said that the evolutionary design technique involves any thinking; random changes were made and the ones that resulted in a configuration that comes closer to the goal behaviour were kept while the rest were discarded. Jay also sees it necessary to point out that the design ONLY worked with the particular chip it was evolved on, it didn't work on "identical" chips manufactured to the same specifications because the configuration was elegant enough to be influenced by imperfections within manufacturing tolerances. Circuits evolved that way were often much smaller, more efficient, and not making sense to human engineers, but they're of little practical use because they mostly only functioned on the particular chips they were evolved on and only near the temperature of the lab where the experiment was conducted.
