I recently attended a very interesting talk from this woman about how she changed her own brain using exercises that simulated deficient areas. While this was very interesting, especially from the stand point of someone suffering with a learning disorder, I was unable to uncover the scientific research behind some of her claims.
Do her exercises help? This seems likely, but I'd like to know if this is proven
Is there truly no drop-off in other, more developed cognitive areas?
And this isn't one of her claims, however, are these exercises better than any every-day activities?
