News feature article in Nature on recent research into the mechanisms of dyslexia, highlighting Sally Shaywitz's work that uses functional magnetic resonance imaging (fMRI). Shaywitz has identified two different pathways of activity in the brain that are used in the process of reading.

... Shaywitz has since repeated the work with 144 children - half of them dyslexic, the rest normal readers. Last year, her team reported that the telltale fMRI signature had appeared once again, bolstering the idea that the underactivation of the parieto-temporal region seen in the brain scans is a key component of the underlying neurological deficit that causes dyslexia.
