left an important thing only-implicit... the relatively-uniform structure of
cortex made it 'difficult' because, well... it just seems 'the same' no matter
where one looks.

that's why it's necessary to understand, and integrate the sub-cortical stuff
before cortex yeilds completely... comprehension of the sub-cortical stuff
'delineates' cortex, 'projecting' onto its relative-uniformity, a
functional-correlation 'map', which one can, then, 'follow', to understanding
of cortex, despite its relative-uniformity.

get it?

in actuality, things went back-and-forth between sub-cortical and cortical
'levels', via many iterations which converged monotonically.

in other words.. things of the TD E/I-minimizer got TD E/I-minimized :-)

more important stuff left only-implicit... =while maintaining minimal circuit
lengths=.

that's what's so wonderful about the 'gyri' and 'sulci' Geometry.

don't miss seeing it for 'yourself'.

cheers, y'all.
