Ooops - this is just an allusion to the fact that right brain
and left brain reign left hand and right hand, however - anyway,
the signals from both poles need to get synchronized which is
done in overcoming the lateralisation of the brain into left/right
by using the corpus callosum, which takes a significant extra time.
They "marry" the parts of ships and the parts of huge turbine rotors,
yeah - they call it that way.
Anyway - synchronizing left/right hand must be understood an be learned,
its in a way, kind of when playing a church organ: the tone you actually
play is delayed through the timeconsuming sonic acoustic...
It means, one better try to avoid callosotomie, BUT as Wikipedia states:
"Kim Peek, a savant and the inspiration behind the movie Rain Man,
was found to be missing a Corpus Callosum."
Boa...
Who knows.
