Dr. Andrew Newberg: It is important to consider both sides of neurotheology very broadly. Thus, the “neuro” side includes brain imaging, psychology, neurology, medicine, and even anthropology. And the “theology” side includes theology itself, but also various aspects related to religious beliefs, attitudes, practices, and experiences. Neurotheology also ranges from considering very esoteric concepts including questions around free will, consciousness, and the soul, to very practical concepts such as understanding how the brain functions and the relationship between spirituality and physical and mental health. This latter topic might be called “applied neurotheology.” Applied neurotheology, therefore, seeks to understand the health-related aspects pertaining to our brain and our spiritual selves. In particular, we can try to understand how being religious or spiritual, or performing various spiritual practices, might be beneficial to our overall health and well-being. In our latest book, entitled Brain Weaver, we consider this important dimension of human brain health.
