is simulating artificial neurons to teach them how to memorize a sequence of
objects. He is using:
http://en.wikipedia.org/wiki/Hodgkin–Huxley_model<http://en.wikipedia.org/wiki/Hodgkin%E2%80%93Huxley_model>
Today at lunch time, I was reading Prigogine (Order out of Chaos,
A nonequilibrium universe, p.229) when me and the neuron guy star a
conversation about the way he simulate de 'real' neurons. He said: is just a
matter of input and output. And I said: and the neuron? the real? Is
nothing? You are simulating despite the 'real'? Form me, a neuron
changes every single instant...because we eat less or more sugar,
alcohol, listen music... read... write, talk, dance breath... but, in the
end, the computer scientist has no intention of simulating the real, just to
imitate the way it seems to behave, work, function... It is just a matter of
creating robots.... to create slaves....

As attachment, I'm sending a text... just emergent writing... and just for
fun.
