The Celebral Code - is it still reliable ?

Hi Brian...

Thanks for your thoughts on The Cerebral Code. I looked at it (the entire
text, along w/most of Calvin's writings are available @his web site,
http://faculty.washington.edu/wcalvin/ .)  I certainly commend him for
making this science freely available.

I see a lot of provocative ideas in his work, esp'ly the application of
Darwinian principles.

The ideas re the triangle and hexagon structures he finds in each layer of
the cortex, excited me the most.

However, IMHO, he doesn't give enough importance to temporal issues - I
think Hebb built on processing of sequences. Not just cell assemblies but
"phase sequences".  And I still think this is the best bet for modeling the
operation of the brain.

I'll confess: tho i think Moby is somewhat in his own little world (like,
I'm not?) I admire and agree with his commitment to processing temporal
information. And Ron Blue, he is closer to my thinking, at least in his
commitment to balance - as he calls it, "correlation opponent processing".
Too bad these guys don't write as clearly as Calvin. Too bad I don't,
either.

So, for those who think there is something to these time based ideas, try
Peter Cariani's site, www.cariani.com.  Neural timing nets - there's a big
idea.

And thanks to Dieter for pointing me there! (couple months ago)
