Please don't loose sight of the fact that the original energy-throughput Q is an
important one. If it seems not to be so, it's "just" be-cause the brain is
extremely-good at keeping it under control... which, when one looks, is seen to
be a gloriously-large clue to all of brain function. In looking at the brain,
the most-important stuff, as far as the brain, itself, is concerned, is the
most-"invisible" stuff. The "invisibility" is a measure of how well the brain
(nervous system) is "engineered" to handle a particular problem. Get it? That
which is "invisible" is right-there visible when we look at it, but the "lens"
through which it can be seen is Thermodynamics.
The cross-correlated inhibition of which you wrote is, of course, of =great=
significance within the larger mechanism (within the global
information-processing dynamics), but we have to see why it's so. Cheers, Ron,
