Title: not about biofeedback!
Review: I was very angry that I had been suckered into buying this book, and the reason I bought it was because, obviously, I was interested in biofeedback. But the book doesn't deal with biofeedback, per se, and in my opinion had no useful information to impart on manipulating brainwaves. As one other reviewer said, a very misleading title. Very, very disappointed in the book. Amateurish.
