: Very briefly, Cook proposed that an important function of the corpus

Does Cook's theory (I'm unfamiliar with it) explain language parsing
in split-brain patients? If not, it seems that split-brain patients 
parsing of language would be incredibly lethargic, when it is not...

: Among other predictions, Cook suggested that his model would help to
: explain the extreme speed and accuracy with which people can
: disambiguate language as they listen to speech or read: The right
(see above)


: 5) Cook never seems to get around to explaining the mechanism by which
: the right hemisphere aids the left.

could it be possible that one hemisphere can take over both jobs?

: The question of the stability of such an iterative process is
: interesting.  So that the reader can investigate it, Cook gives a
: MicroSoft BASIC program to simulate it and even to compute the
: resulting artificial EEG signal produced by the simplified artificial
: brain as it "thinks."  Unfortunately, he doesn't show any results of
: running this program, only refers to some earlier papers.

Can someone type this in and get it to the net?
I'd love to examine it....

: If it doesn't terminate, does that suggest a mechanism for the "monkey
: chatter" of thoughts that Eastern meditation attempts to suppress?
