Re: [xmca] self-regulation

[Martin Packer <packer@duq.edu>]

Yes, I too have Fuster's book, and he draws no distinction between the two prefrontal areas. Goldberg's argument goes further: he suggests that the traditional account -- that the the right hemisphere is involved in spatial cognition, while the left is involved in linguistic and perhaps musical and logical cognition -- is incorrect, or at best an oversimplification. He presents evidence that the left hemisphere handles cognitive strategies that have become routinized, while the right hemisphere is involved in exploring novel situations to which existing codes and strategies are not applicable. The traditional language/nonlanguage dichotomy may simply be a special case of this functional differentiation. In addition, as a task becomes routinized it may be moved from the right to the left hemisphere.

Yet Fuster still titled his book The Prefrontal Cortex (singular) as if the prefrontal cortices were one unitary area of the brain (using the customary terminology but never-the-less inadvertantly perpetuating the same misconception.)

I also wonder what brain imaging technology would show about the development of executive function in the prefrontal cortices in deaf people. I think it has been a mistake for neurologists to refer to the prefrontal cortex as if the left and right prefrontal cortices acted in unity.  There must be different self-regulatory systems operating from the left prefrontal cortex (speech) and perhaps some other type of non-verbal self-regulation operates from the right prefrontal cortex.This other type of non-verbal self-regulation could be left prefrontal in the deaf. Brain imaging techniques like the functional MRI could provide a breakthrough. Since Vygotsky was focused on the ability to self-regulate conceptual thought we can expect that self-regulation of sensori-motor functions is going involve the development of a different neurological system.
