RE your last conjecture: if the query WAS just for "humoristic
research", it certainly succeeded! I, for one got a big laugh out of
your authoritative-sounding pronouncements, which mixed
indiscriminately some facts, some nonsense, and some garbled mixtures
of the two.
An example of the latter: one hand strangling the wife, the other hand
trying to restrain the strangling hand. I doubt very much whether this
has ever happened with a (surgically) split-brain patient. Sounds like
an exageration of the kind of thing one might see in an ALIEN HAND
case. (Yes, I have had a patient with alien hand syndrome. A friend
of mine has studied alien hand syndromes extensively. I leave it to
you to look it up and learn why this differs from split-brain cases.
Or just to learn, period.)
Missing the point: the fellow asked if right brain controlled left body
and vice versa. The simple answer is, "yes". You confuse the issue by
citing retinal projections: yes, this an APPARENT exception, in that
both eyes project to both hemispheres (note: even this reverses the
question of contralateral BRAIN control of the BODY), but the left
visual field projects to the right hemisphere and the right visual
field projects to the left hemisphere.
Can you cite any data supporting your insinuation that bimanual
coordination in skilled tasks is impaired by corpus callosum section?
Never mind "skilled" movement: do such patients have problems walking?
i.e. each leg going at its own pace? one staying while the other is
going? both trying to step forward at once?? You ought to have your
head examined. Or at least you ought to learn a little more before you
pop off like you know something about these things.
As regards the pop psych machismo interpretation of hemispheric
communication, the old horse-shit about reptiles, mammals, etc.--give
us a break!!
Bytheway: email must be slow in your neck of the wooods. This was
discussed to death in this newsgroup many weeks agoo.
