Sorry - cross-posted inadvertantly - I usually post in
"TD E/I" is shorthand for the Topologically-Distributed ratio of
Excitation to Inhibition. In theoretical work I've done, I've proven
that nervous systems are structurally ordered throughout their entire
extents to do only one thing, minimize TD E/I.
Behavior, cognition and affect are produced as by-products of this
underpinning biological 'goal', to the degree that it is, in fact,
