My Stroke of Insight by Jill Bolte Taylor
On the morning of the 10th December 1996, Jill Bolte Taylor, a thirty-seven-year-old Harvard-trained brain scientist experienced a massive stroke when a blood vessel exploded in the left side of her brain.
A neuroanatomist by profession, she observed her own mind completely deteriorate to the point that she lost the ability to walk, talk, read, write, or recall any of her life, all within the space of four hours. As the damaged left side of her brain - the rational, logical, detail and time-oriented side - swung in an out of function, Taylor alternated between two distinct and opposite realities: the euphoric Nirvana of the intuitive and emotional right brain, in which she felt a sense of complete well-being and peace; and the logical left brain, that realized Jill was having a stroke and enabled her to seek help before she was lost completely.
