Summary: left-handers' brains *are* different


A recent article in "Science News" points out that left-handers
and the abidextrous have a physiological difference in their
brains from right-handers.

The region that connects the two sides of the brain is the
corpus callosum.  In left-handers and the ambidextrous, this
region is ~11% larger than that of right-handers'.

It has not been made clear yet *why* the difference in size, but
if it is because of more connections between the two hemispheres
it might be a physiological reason for why lefties and ambis
show more of a sharing of brain function thoughout the hemispheres,
and why lefties are more ambidextrous than righties.
