To this, I respond that A may still | >contribute to B and thereby ultimately contribute to C. | | There are people who suggest that physical laws regarding | parity-violation may relate to the fact that biological amino acids | tend to be in l- form while sugars in d- form but even those are | highly suspect and must be regarded as speculative. Most people think | it to be merely a historical accident. However suggesting that the | developmental processes of a whole organism to be controlled by such | physical laws is, simply put, ridiculous. If you want to make such a | suggestion, it is up to you to describe a mechanism by which it could | happen and give some evidence to indicate that your mechanism is, | indeed, at work to the exclusion of alternatives. Hi, Dr. Norman, I've read the OP in this thread, and the post quoted above. =ALL= of this stuff has been Resolved in AoK, in particular, in Ap6, all along, there being reduced to TD E/I-minimiz- ation 'within' the "special topological homeomorphism of central nervous systems" [AoK, "Short Paper"], includ- ing the information-processing ration- ales of stuff like "cortical stripes", "cort- ical columns", the union of symmetry and asymmetry amongst the various cortical areas, and how and why every- thing is Simply-Ordered in TD E/I-min- imization. The 'presumption' that "left" and "right" hemispheres 'are functionally-differen- tiated is Unsustainable because the corpus callosum connects the hemi- spehres massively, which is =in= the special topological homeomorphism. When folks sever the corpus callosum [and the other commissures], the re- sult is not a "nervous system" but an artificially-instantiated entity that is no longer a nervous system. Then, folks 'presume' what the latter does is what "nervous systems" do, which is False. When the corpus cal- losum is severed, the result is anal- ogous to taking a knife to some of the "bus" circuits in a computer -- af- ter doing so, the thing is no longer a "computer", and, if any 'functionality' remains, that 'functionality' can only be interpreted with respect to the formerly-globally-integrated circuitry. There exists no "purpose" -- no ac- tual functionality -- in what remains of the artificially-altered circuitry. Folks who interpret "split brains" ex- periments as 'disclosing-function- ality' are just looking at artificially-al- tered stuff without remembering that, since it's artificially-altered, no matter where they look in "the brain", they're only seeing subsets of 'normal' func- tionality. Not comprehending global- ly-integrated-TD E/I-minimization, they 'presume' that the =partial= stuff 'is what normally occurs' in nervous systems. It isn't. It's a =deficit= cond- ition, no matter where one looks in artificially-altered 'brain'. The "left-right" stuff is 'just' a subset of the how and why the special topol- ogical homeomorphism instantiates on-the-inside-looking-out-ness with respect to consciousness, cognition, behavior, affect, etc., as has been dis- cussed in AoK all along. The 'differences' between the hemi- spheres correlate with stuff like the differences between a "right-arm's" and a "left-arm's" coordinated behav- ioral necessities -- it'd be completely [and absurdly] -dysfunctional if the same-stuff [the same neural dynam- ics] occurred in, say, left and right primary motor cortices that activate "arm" musculature. =All= of the so-called ~"hemispher- ical functional biases" are exactly like this with respect to globally-in- tegrated TD E/I-minimization. 'normal' nervous systems are 'wired- up' in minimal-distance ways with re- spect to the =one=, globally-integrated purpose of achieving TD E/I-minimiz- ation [AoK, Ap9.] This minimization of circuit lengths that's in TD E/I-minimization distrib- utes functionality, and, hence, guides neural plasticity, and 'local'-functional- ity-differentiation in ways that derives solely in experience. The Genome is optimized to do =that=, not the other way around. [I discussed how and why the genome is activated and driven by experience- determined 3D-E ["3D-Energydynamics"] during my last online 'life', doing so all the way down to just-energy.] Anyway, it's all been in AoK [and the Refs cited in AoK], all along. Cheers, Dr. Norman, k. p. collins
