On a December morning in 1996, neuroanatomist Jill Bolte Taylor suffered a stroke. It was a learning experience. "How many brain scientists have the opportunity to study their own brain from the inside out?" she said. "In the course of four hours, I watched my brain completely deteriorate in its ability to process all information. On the morning of the hemorrhage, I could not walk, talk, read, write or recall any of my life."
