Dr. Andrew Newberg is a neuroscientist who studies the relationship between brain function and various mental states with a focus on altered states of consciousness outside those produced by existing psychedelic compounds. He is a pioneer in the neuroimaging and neurological study of transpersonal experiences, which are highly correlated with positive enduring treatment outcomes in psychedelic therapy. Dr. Newberg is the author of The Varieties of Spiritual Experience and a number of other books largely focused on how brain function is associated with various mental states - in particular, religious and mystical experiences.
