	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.
