Your Brain on Mysticism

            
If you have ever found yourself face to face with a ghost or seemed to float through time and space in an out-of-body experience, then you are one of the many who has had a mystical experience. Mystical experiences are thought to be the backbone of religious beliefs and have occurred across all cultures throughout human history. Although they are such a widely reported phenomenon, very little research has actually been done on why exactly they happen.
            Dr. Jordon Grafman of Northwestern University conducted a study examining the neural correlates of mystical experiences. Previous research has indicated that the dorsolateral prefrontal cortex (dlPFC) may be important in regulating mystical experiences. 
In earlier studies, the dlPFC showed decreased activity during prayer or religious exercise. Stronger activity of the dlPFC has also appeared in skeptics compared to believers, suggesting that believers might experience down-regulation in the dlPFC (Grafman). Using this knowledge, Dr. Grafman and his colleagues studied patients with brain injuries to the dlPFC or temporal lobes and predicted that impairment of the dlPFC would be associated with greater mystical experiences and that lesions to the temporal cortex would be associated with less mystical experiences. The results of the study indicated that their predictions were correct. Patients with lesions to the temporal cortex did not differ with healthy controls in amount of mystical experiences, while patients with focal lesions to the dlPFC experienced far more mystical experiences (Grafman). According to the authors of the study, these results could imply that the dlPFC plays a role in constraining naïve interpretations of the meaning of perceptual experiences. That is, the dlPFC prevents us from jumping to conclusions and labeling hard to explain phenomenon as supernatural.
David Rand, head of Yale University’s Human Cooperation Laboratory has another theory as to why some people might be more religious than others, and therefore more prone to mystical experiences. According to Rand, whether a person is deliberative or intuitive is the deciding factor on one’s level of religiousness. A deliberative person is more likely to think carefully and find a rational reason for his or her choices, while an intuitive person will often just go with his or her gut. Intuitive people, according to a study by Rand, are more likely to be religious or have a stronger belief in God (TIME). In his study, Rand and his colleagues used the Cognitive Reflection Test, which measured a person’s level of intuition and deliberation based on how they answered questions. Intuitive answers made some sort of sense, but were ultimately incorrect. Those who made more intuitive answers typically had a stronger belief in God (TIME). Therefore, patterns of thinking can determine how religious one is or isn’t. 

So, if someone is intuitive and seems to see a ghost, that person is more likely to interpret that scenario as mystical rather than try and come up with a more logical explanation. Is this related at all to Dr. Grafman’s study and the dlPFC? Possibly. If the dlPFC prevents us from making intuitive answers, could it be that deliberative people simply have a more active dlPFC? I’ll leave that question here for further research.
