Robert... yep, it's pretty-well hammered out... although it's not yet 

There are many neuroanatomical instances such as the retinal one which 
you note... the retina is upside down and left-right reversed... the 
primary sensory mappings are upside down and left-right reversed... such 
is a "theme" that repeats over and over again... all to bring the 
neuroanatomy into allignment with the "simple" TD E/I minimization 
dynamics that I described in an earlier msg... ken collins
