It appears as if YP Fun <ypprotection@yahoo.com> asked:

|Can you imagine two brains sharing the
|same sensory inputs and outputs?

Yes, sort of. The human cortex actually forms two brains, both sharing the
external inputs. Most humans don't even notice they have two of the these.
Those who have a severed corpus callosum will have two brains which do NOT
communicate, which can create a confusing situation if one brain get some
input and the other does not, and the person is expected to respond to that
information.

|The whole concept of threading is beyond
|nature. Is there anything in nature capable of
|multithreading. All human beings are singly
|threaded. We live life over a single thread.
|We can NEVER do two things at the same time
|at any given time.

Interesting hypothesis. What experimental data do you found it on?

|In a dual processor computer two threads
|can run at the same time and they may act
|either independently or in conjunction with
|one another. Not only that, but a root thread
|can govern, control and spawn many child
|threads. If a program is concious, when
|it executes it need never loose control,
|just because it forks.

This corresponds somewhat to the human condition when you don't work a
problem and suddenly the solution comes ``out of thin air''. Some part of
you did the thinking (unless you subscribe to telepathic distributed
thinking, or some other esoteric solution to this situation. :-)
