Oh, great. Thank you; I'd (obviously) only known about the eye

It was more having to do with synapse selection (or at
least selection by non-removal); if information is being passed from one
side to the other, then possibly that process could be influenced for the
better. Admittedly, the best means would be practice with stuff that used
both sides and required their cooperation, but some easier means would be nice.
