While not a neurophysiologist, I still recall that, as I understood
it, the optical path (perhaps as far as the retina) also modifies or adds information to the array even before it gets to the cortex; if so, then it would seem that the array which arrives at the cortex is not necessarily a "perfect" topologic or geometric representation of
the external world scene.
And this would imply that what the frontal lobes receive is a triply processed, compressed or modified representation...
And this is probably the result of a need for efficiency in threat
analysis, a throwback to our animal precursors...
The classic case (discussed here before with respect to diagonal frameworks in architecture) is the reaction to diagonal lines on the cat retina- if I remember, the retina itself reacts strongly to diagonal visual stimulus, long before the signal reaches the visual cortex, let alone the frontal areas...
The unease with which Per's designs are greeted, may be partly due to a primordial "danger" reaction to diagonals; which, of course, is
paradoxical, given the quite self-evident role of diagonals in adding
strengthg to structures....
