Neurotheology is a study of neuroscience and spirituality. It focuses on how spiritual experiences, revelations, and epiphanies affect our neurological system.
Although shamanism has been practicing this for thousands of years, shamanism is more focused on the spirituality aspect - healing and having these experiences, rather than doing actual neuroscientific studies to prove it's positivity, and capability to help many people.
"While the term neurotheology is new, the basic ideas have been around for thousands of years" says Dr. Michael Winkelman, Department of Anthropology, Arizona State University. "Many cultures have developed technologies for altering consciousness and inducing spiritual experiences." Winkelman describes shamanism- an ancient healing practice- within the context of neurotheology.
