You are actually right on the money Richard. If you read the book "The
brain that changes itself" by Norman Doidge, he proves the remapping of the
brain due to activity, even in blind people. He even did research on making
completely sighted people blind for awhile and scanned how the brain
remapped itself when they learned braille, etc. Touch took over the visual
cortex. A GREAT read.
