Resumen de Dyslexia's roots traced to bad chat in the brain
The neural basis of dyslexia may finally have been nailed. It seems that different areas of the brain's language network don't communicate properly. The discovery may lead to ways of helping people with dyslexia improve reading and writing skills. One theory proposes that people with dyslexia have subtle hearing problems, particularly involving timing of speech, which in turn leads to the brain's neural representation of phonemes--the basic units of speech sounds--developing poorly. The trouble with this idea, says Sophie Scott at University College London, is that people with dyslexia have no problem understanding speech. To investigate, Scott and her colleagues scanned the brains of 23 adults with dyslexia and 22 without. The findings suggest that the poorer the connectivity between these regions, the worse participants performed on reading and other phonological tasks.
