Sally and Bennett Shaywitz at Yale have used brain scans to show that dyslexics have too little activity in the back of the brain and increased activity in the front.
The Scanner
The fMRI machine: Gauges the brain's activity while the child reads words off a screen. The child answers questions like this one: do these nonsense words (LETE JEAT) rhyme?
The scan
Normal brain: Links letters the child sees on a page to sounds, then puts the sounds in sequence to form words
Dyslexic brain: Cannot do these tasks well; tries to compensate by relying on the area responsible for producing speech
