To the best of our knowledge via the Wisconsin Reading Coalition:

Jim Fleming: Maryanne Wolf knows as much as anybody on the planet about what the human brain is actually doing when it reads. She runs The Center for Reading and Language Research at Tufts University and enjoyed significant popular success for her last book, “Proust and the Squid: The Story and Science of the Reading Brain.” But as Anne Strainchamps found out, Wolf is equally passionate about the dyslexic brain.
Maryanne Wolf: I like to say that the dyslexia brain is proof and daily evidence that the brain was never wired to read. Now there are all these children in the world, all these individuals are walking around with brains that are so often, I can’t say that for every single person, but so often these are brains that are wired to see spatial patterns, to see the big picture, to go outside of the box, to think holistically. Often they’re artists, they’re architects and yeah, that same advantage or set of advantages which made them before literacy, our generals, out builders, a lot of our great figures, that made a disadvantage at the same time for some of the wiring that goes into left hemisphere language processes.
Now the real, if, if you wanna know my real task in life, it’s to re-conceptualize or to help re-conceptualize dyslexia from being thought of as a deficit or something wrong with the brain, to realizing this is an extraordinary and beautiful brain that we have failed as an educational system to know how to teach easily when it comes to reading. But that is the failure, not the child, but of us to understand.
And one of the joys for me in brain imaging is that we’re able to look and see how many of our individuals with Dyslexia have such interesting right hemispheric processes, and when you look at how t hey read are using the right hemisphere inefficiently for a left hemisphere-like task.
