local distinctions make patterns; this is flocking behaviour and so your
quantitative emphasis is lacking something.
The synchronisations that take place in neural columns/networks etc make the
the groups fire as 'one' and so a filtering process -- local to general
which in turn becomes local to a 'higher' level. The hierarchy is WELL
documents in neurology etc and so you single context perspective is, IMHO,
meaningless; it is just an expression of numbers.
These sorts of abstractions, local to general and 'up' of 'down' a level are
in our senses, your visual system has already abstracted before it gets half
way through the brain and that favours sameness/difference,
object/relationship distinctions (fovea/parafovea does this. IMHO you are
looking too closely at the dots rather than the patterns since it is the
patterns that lead to behaviour etc. You see this in studies of neurology
where they zoom-in to a surface and see interdigitations, resulting from
recursive dichotomisations, and cant see the expression (e.g. the
interdigitations of the fight/flight on the 'surface' of the amygdala). The
expression is a few steps 'back'; it is as if you are looking at a B/W
picture and only see the dots, no image. In a carpet you are looking at the
warp and so bypassing weft and the expression that the combination leads to.
Take a step back Joe, see the forest and beyond.
Chris.
