They seem to be assuming that if you stimulate the "healthy" hemisphere,
you feel better and then use that to find which one of their hemispheres

eye patches won't work. IIRC, there's signals going from both eyes to
both hemispheres, but the right side of each eye goe to the left
hemisphere, and the left side from each eye goe to the right hemisphere.
