In 1997, a book titled A Change of Heart was published that described the apparent personality changes experienced by Claire Sylvia. Sylvia received a heart and lung transplant at Yale–New Haven Hospital in 1988. She reported noticing that various attitudes, habits and tastes changed following her surgery. She had inexplicable cravings for foods she had previously disliked. For example, though she was a health-conscious dancer and choreographer, upon leaving the hospital she had an uncontrollable urge to go to a Kentucky Fried Chicken outlet and order chicken nuggets, a food she never ate. Sylvia found herself drawn toward cool colours and no longer dressed in the bright reds and oranges she used to prefer. She began behaving in an aggressive and impetuous manner that was uncharacteristic of her but turned out to be similar to the personality of her donor. Interestingly, uneaten Kentucky Fried Chicken nuggets were found in the jacket of the young man (her donor) when he was killed.
Among the consultants for the book were Dr. Paul Pearsall, PhD (author of "The Heart's Code: Tapping the Wisdom and Power of Our Heart Energy" and many more books) whose name appears as an author of a paper co-written with Dr. Gary E. Schwartz, PhD (author of many books including "The Afterlife Experiments: Breakthrough Scientific Evidence of Life After Death") and Dr. Linda G. Russek, PhD (co-author of many books including "The Living Energy Universe: A Fundamental Discovery that Transforms Science and Medicine" with husband, Schwartz).
Claire Sylvia's book and some of the books by the PhDs mentioned above have all been endorsed by that giant of scientific reason, Deepak Chopra. Some of the books written by the aforementioned doctors have also been co-authored by Chopra.
Does cellular memory exist? Were the studies conducted by these doctors published and peer-reviewed in a recognised journal and has there been a proper investigation that confirms or debunks these studies? I would also like to know if the credentials of these authors are genuine as some sites have cast doubts over them.
