"How many brain scientists have been able to study the brain from the inside out? I've gotten as much out of this experience of losing my left mind as I have in my entire academic career."
Jill Bolte Taylor (TED talk video at source)

"I was very masculine and patriarchal and had been developing the animus, the left brain, all this time. Now the right brain'the feminine... power, the earth power - came and hit me. It opened up the whole dimension of the feminine, of the earth, and so on." Father Bed Griffiths after suffering a near fatal stroke to left hemisphere.

Dr. Richard Alpert, now Baba Ramdass, had great spiritual insight after a stroke. don't know the link.

I’ve been recommending “My Stroke of Insight” to everyone I know. It’s the best book I’ve read all year! You can get Jill's book from Amazon for a good discount.
