Dyslexia and the ecological brain.

Evidence is available to show that normal and disturbed reading is a bilateral rather than an unilateral hemispheric affair. The primary subservience of reading seems to shift from right to left during the development of the learning-to-read process. Since the brain is sensitive to enriched stimulation from the environment, hemisphere-tied dyslexia may be alleviated by selective or alluding stimulation of the right (L-dyslexia) or the left (P-dyslexia) cerebral hemisphere. In general, the results of experimental group and single-case investigations show the fruitfulness of these neuropsychological treatment procedures. However, it is apparent that there are questions that remain to be answered.
