Subject: [alt-beam] Re: Multiple Inputs for Nv neurons

OK this is going to be hard to explain but bear with me. I think that rob =
is on the right path, concider the multitude of loops in a brain, I think t=
hat the interconnection between each loop could depend upon outside influen=
ces such as nerve endings. Like the different parts of the brain controlli=
ng different parts of the body and reacting to the inputs from those parts,=
lets assume (big, big, huge assumption) that in the brain, 1 Nv loop is a=
ttached to 1 nerve ending on the tip of a finger, you touch something, the =
nerve ending acts like a PNC and starts the loop, the output from the loop/=
chain goes somewhere else and tells another loop/chain something eg. the lo=
op attached to a finger muscle telling it to stop the finger moving forward=
. Now all we have to do is take the same approach and use 1 loop/chain per=
output/feedback and have the feedback act as a PNC to other loops. Do you=
get what I mean?? It makes sense in my head.
Not bad huh, I have been into beam for a month and made the breakthrough be=
tween real life and Alife {;-)
Save a copy of this e-mail, as it will make me famous, ohHoHohahaha (meant =
to be a mad scientist laugh)
Either that or I am just starting to understand what Tilden is on about. {=
