This week we're looking at brain injuries, and the ways they change the lives of patients. We'll talk to Jason Padgett and Maureen Seaberg, authors of "Struck by Genius: How a Brain Injury Made Me a Mathematical Marvel." And we'll speak to neuroscientist Dr. Adrian Owen about his brain imaging research detecting awareness in vegetative patients. Note: The article Accidental Genius by Darold A. Treffert can be found on page 52 of the August 2014 issue of Scientific American.
