These searchings for sustain the sight that the stability of phonological representations plays a crucial role in the success of written language handling which lesion location within the perisylvian language area accurately generates a dissociation in between phonological dyslexia/dysgraphia and the sublexical phoneme-grapheme conversion processes required for non-word analysis and punctuation (Coltheart, 2006).
