Neurotheology

It is a subject written about in John Horgan's book "Rational Mysticism." It is an interesting book in that it explores the intersections of science and spirituality. One of the topics covered is the study of brain chemistry as it relates to spiritual experience. Much of the book veers off into pseudo-science and faux spirituality, but the study of brain chemistry seemed like pretty hard science. Keep your ears open for this topic in the near future, as it may make claims that are insightful, or troubling, or fascinating. It is too early to tell.
