Last night I went to Nashville to listen to Susan Barton from Bright Solutions speak and it was amazing. She is brilliant and she knows so much about dyslexia and to be in the same room as her was just wonderful. She spoke for 3 hours about dyslexia and dysgraphia and I took pages and pages of notes. One of the things I learned is that there are in fact differences in the brains of dyslexics and non-dyslexics.
All brains have two hemispheres, a left and a right. A non-dyslexic brain has a larger left hemisphere compared to the right. Turns out that in a dyslexic brain both hemispheres are the same size, the right hemisphere is 10% larger than a non-dyslexics right hemisphere. Which just goes to show that being dyslexic doesn't mean you aren't smart, you actually have more brain than the rest of us. ;)
