You know, I mentally drafted a response to Chad's question and it was
spookily, uncannily, exactly the same. Even down to the order of the
points, the initial "no-one knows how" and then "however". All I would
add is that the most accurate answer that could be given is which
regions of the brain increase their blood supply when these kinds of
tasks are performed.
I must be honing my didactic skills!
Thanks for your questions Chad - even when there is no answer it's a
great reminder of the gulf between what we know and what we would like
to know ... !
