The brains studied were dead and there is no federal agency of find out that the living brains of dyslexics would display the uniform damage in the left hemisphere that the dead brains did. Another problem is that only dyslexics were studied - the results were not compared to non-dyslexics therefore it cant be give tongue to whether this...
