A stroke of insight

My mother's brain is being eaten away by Alzheimer's. That's one reason why I found this video of brain researcher Jill Bolte Taylor so fascinating. But not the only reason.

Taylor had a massive stroke and lived to tell about it. The experience gave her new insight into how our brains function, and into that place in the brain's right hemisphere that she calls "nirvana."

The video, posted on ted.com, is titled My Stroke of Insight.
