What happens in the brain during a spiritual experience?

The question as to what happens in the brain when we have a spiritual experience has been explored numerous times, with varying results, and it continues to fascinate researchers and non-specialists alike. A new study aims to reveal more.

 

For decades, researchers who are intrigued by the importance of spirituality in people's lives have conducted studies investigating what happens in the human brain when people feel deeply spiritually connected.

 

Due to the fact that the concept of "spirituality" can be understood in so many different ways across cultures and individuals — and that whatever someone may term a "spiritual experience" can stimulate the brain in very complex ways — it has been hard to pinpoint a brain mechanism for spirituality.

 

Nevertheless, researchers have persevered despite the challenges. So, studies on Carmelite nuns and dedicated Mormon practitioners have suggested that multiple brain regions are involved in processing experiences of union with a higher being.

 

Also, a commonality suggested by a few studies was that individuals engaging in long-term spiritual practice had decreased activity in the right parietal lobe, which has been tied to self-oriented focus.

 

In other words, spiritual experiences seemed to increase, as it were, selflessness in the brain.

Spirituality against depression?

Prof. Lisa Miller, the editor of the Oxford University Press Handbook of Psychology & Spirituality, has conducted a series of studies on what happens in, or to, the brains of people with intense spiritual lives.

 

Her research has indicated that people with habitual spiritual practices show cortical thickening in the prefrontal cortex. Intriguingly, she says that individuals who live with chronic depression experience cortical thinning in the same brain region.

 

This has led her to argue that spirituality and depression are likely "two sides of the same coin."

 

Recently, Miller and a team of researchers from the Spirituality Mind Body Institute, at the Teachers College of Columbia University in New York City, NY, and the Yale University School of Medicine in New Haven, CT, have used functional MRI to find out what happens in the brains of individuals as they picture an intense spiritual experience.

 

They recruited participants subscribing to different spiritual and religious practices, whom, in a first experiment, they asked to remember a personal spiritual experience as their brains were being scanned.

 

This was done with the help of guiding scripts that the participants received beforehand, instructing them "to describe a situation in which [they] felt a strong connection with a higher power or a spiritual presence."

 

Since they all had widely different spiritual practices, the experiences described in the experiment prompt spanned an extensive range, from "a two-way relationship with a higher power" and "a felt sense of oneness in nature by the ocean or atop a mountain" all the way to "being in a zone of intense physical activity (such as sports or yoga), sudden awareness, bodily felt connectivity or buoyancy, meditation, or prayer."

 

None of the prompts included any imagery related to food and eating, sexual activities, or drugs.

 

The researchers argue that this is emblematic of "a broader, modern definition of spirituality that may be independent of religiousness."

 

Their findings have been reported in an article now published in the journal Cerebral Cortex.

Spirituality may 'buffer the effects of stress'

Studying the volunteers' brain activity as they pictured a personal spiritual experience allowed the scientists to identify the brain regions that seemed to be involved in processing spiritual events.

 

Miller and colleagues also compared the brain activity observed as the participants described a spiritual experience with the brain activity seen as the volunteers imagined either stressful or neutral experiences that did not trigger any strong emotions.

 

In doing so, they were able to find a pattern that they say is only observed when a spiritual experience is involved.

 

They found that the inferior parietal lobe — which has been tied to a person's awareness of the self and of others — was less active when they were describing a spiritual event, whereas the activity in that brain region increased when they thought of stressful or emotionally neutral experiences.

 

So, the team suggests, this region "may contribute importantly to perceptual processing and self-other representations during spiritual experiences."

 

This appears to confirm Miller's previous arguments that spiritual experiences could help to "buffer the effects of stress on mental health."

 

"These results demonstrate neural mechanisms underlying spiritual experience across diverse traditions and perspectives," the researchers explain.

 

"Continuing to build our empirical understanding of how spiritual experiences are mediated by the brain and the future extension of similar studies to clinical populations could help facilitate the judicious integration of spirituality into treatment and prevention in areas of mental health conditions," they add.

 

It is worth mentioning that the study was small-scale, involving only 27 participants in total. All of the participants were young adults, 18–27 years old, and in good physical and mental health.

Just as a reflection, what might be called a SPIRITUAL EXPERIENCE is quite different for each individual.  For many people, political activity is a spiritual experience and this explains some aspects of political fanaticism and why sometimes is so hard to convince those political fanatics about their erroneous points of view. A typical example is that of Hitler and the nazi ideology or the apparent blindness of communist militants in face of the real situation that was prevailing in Eastern Europe and the URRS under communist rule or those who somehow feel that Cuba is the paradise: they experiment politics a a spiritual experience!

With respect: Spiritual experience can't be put into words, let alone be talked about or measured; it is never seen anything to be achieved (it happens!) or anything that makes the "experiencer" proud or boastful; and "political" or any human endeavour will never be confusing or something to be shunned and all endevours will be seen for what they are. 

 

Thank you,  @Luisam.
