This brings up a question. Will these circuits purely acquired by training? Then they have to be developed by training in every single reader. Or will the brain eventually mutate and change its structure to accomodate such new circuitry? But we consider mutations have to be haphazard and natural selection is selective. So is this new literacy putrely cognitive (developed through training) or can it be or become genetic? Is there a study about teh connection of autistic savants and such new literacy?
