THE SPIRITUAL DOORWAY IN THE BRAIN - KEVIN NELSON
Although the main text was both interesting and informative, and my mind was posing questions, solutions, and theories as I progressed with reading the text, the conclusion chapter was a rather weak let-down. Had that stood up to the same invigorating excitement provided by the main book, I would have rated it higher. It was an anti-climax, in that it offered no set solution to the investigations detailed throughout the main text.
I would recommend the book to those interested in NDE's, spiritual activity in relation to physicality, and those interested in reading layman-texts on neurology.
