removal of a hemisphere etc shows the other side adapting -- which is
emphasised in what I write in that the left/right behavioural
characteristics are biases and there is scope for change -- especially in
the young. Remove at a later stage and this plasticity is not so good.
Current technology allows blind people to see but they often drift back into
living in the dark .. they cannot see without continuous practice -- they
have not developed the HABIT of seeing as infants can do.
Re brain areas, I emphasise MacLean's Triune brain concept that is in
'threes' but I think if you look carefully at the development process you
are 'seeing' bifurcations at work. Thus the more anterior you are the more
bifurcations, the more abstract thinking etc (even MacClean has emphasised
the Cingulate Cortex as being another area - it is 4 layers 'deep', Limbic
is 3, R-complex 1 and neocortex 6. Maclean has demonstrated novel behaviours
associated with the Cingulate cortex and so a 'distinct' area.)
The R-complex is more of a single context frame of mind, very EITHER/OR.
There is a mechanical emphasis (if hot -- move, if cold - move). In the
limbic system you see the first obvious bifurcation, the primitive
hemispheres here favour general preservation of the self (left bias) vs
preservation of the species (right bias)
IOW the 'trunk' has developed branches, the left is 'like' the reptilian, a
refinement of it and the right introduces FEEDBACK processes that allow for
LEARNING. This area is more biochemical in operation and that includes more
subtle responses to environment -- if cold, shiver, if hot, sweat. This
shows a REFINEMENT in behaviours.
Carry on the development and the trunk keeps going into the left bias of the
neomammillian brain and the 'branch' keeps going into the right. But this
development is bifurcations such that the posterior of the neocortex is more
concrete in processing when compared to the anterior parts and at the same
time behavioural characteristics of 'trunk' or 'branch' become even more
entangled such that you see left/right behaviours reflects in lobes in BOTH
sides.
Furthermore the behavioural characteristics either side of the Sylvan
Fissure suggest another level of bifurcation, where the posterior side is
more 'reactive' and the anterior side more 'proactive'. Get down to the
frontal lobes and there is intense interdigitations (right-left-right-left
etc see Goldman-Rakic's work on this) and planning etc with strong emphasis
on dynamic processes based on the underlying oscillations (which you seem to
have ignored in your comments -- tsk tsk Dees.)
Overall what comes BEFORE sets the context, the GENERAL characteristics, of
what comes AFTER but what comes AFTER can also include 'novel' forms.
Re your book list -- read it long ago, does not change anything re
left-right oscillations etc and the calculus of indications allows for
symbolisms of BOTH/AND states, Necker cube oscillations etc in simple
ways...
