Spirituality – Brain Location

I read that 80% of people sampled around the world said they were Spiritual or Religious. Is there a center or spot in the human brain related to spirituality and religiosity?

The results of a study published in Biological Psychiatry reported that spirituality (“spiritual acceptance”) appears to be located in the brain stem in a specific brain circuit known as the PAG, short for periaqueductal gray. PAG functions include altruistic behviors, pain modulation, unconditional love, and fear conditioning. Michael Ferguson, PhD, principal investigator, was quoted as saying, “Our results suggest that spirituality and religiosity are rooted in fundamental, neurobiological dynamics and deeply woven into our neuro-fabric. Why do only an estimated 80% of individuals on Planet Earth define themselves as spiritual, religious, or both? Why not 100%? Good question. My guess is because the brain is also desirous of “free choice,” and a myriad of risk factors may help to determine free choice for each individual.
