as is explained in AoK, Ap8, it's the chronically-elevated TD E/I that
constitute the main neural dynamics underpinning what's been referred to
as 'depression', which include a lot more than 'memory'-addressing
what's been referred to as 'depression' is 'just' innate functionality
that functions to 'dampen' what would, otherwise, be the supersystem
configuration (AoK, Ap5) consequences, given the chronically-elevated TD
what's referred to as 'depression' =saves= Lives, both of the
'depressed' individual, and amongst those with whom the 'depressed'
it's been the Ignorance that's prevailed with respect to what's referred
to as 'depression' that's been the Killer.
