Beauregard M, Paquette V. (2006). Neural correlates of a mystical experience in Carmelite nuns. Neurosci Lett. Jul 25; [Epub ahead of print]The activation conditions compared in the figure above are the Mystical condition, in which subjects were asked to remember and relive (eyes closed) the most intense mystical experience ever felt in their lives as a member of the Carmelite Order vs. the Baseline condition, which was the "resting state" with eyes closed.
The main goal of this functional magnetic resonance imaging (fMRI) study was to identify the neural correlates of a mystical experience. The brain activity of Carmelite nuns was measured while they were subjectively in a state of union with God. This state was associated with significant loci of activation in the right medial orbitofrontal cortex, right middle temporal cortex, right inferior and superior parietal lobules, right caudate, left medial prefrontal cortex, left anterior cingulate cortex, left inferior parietal lobule, left insula, left caudate, and left brainstem. Other loci of activation were seen in the extra-striate visual cortex. These results suggest that mystical experiences are mediated by several brain regions and systems.

Mystical experience is characterized by a sense of union with God. It can also include a number of other elements, such as the sense of having touched the ultimate ground of reality, the experience of timelessness and spacelessness, the sense of union with humankind and the universe, as well as feelings of positive affect, peace, joy and unconditional love.However, the experiment did not involve direct induction of a "mystical experience," but rather a memory of one. Importantly, the Control condition asked the nuns to remember and relive (eyes closed) the most intense state of union with another human ever felt in their lives while being affiliated with the Carmelite Order. So the important contrast is "remember union with God" (Mystical) vs. "remember union with human" (Control). Here's the list of brain areas more active in the former:
a Carmelite has given her life totally to Jesus Christ. She desires to follow Him and belong to Him completely.[BTW, check out the flashy Carmelite Web Site]
The average intensity of the subjective experience was 3.06 ± 0.93 (range: 2–5) during the Mystical condition and 3.04 ± 0.80 (range: 2–5) during the Control condition.After the scan, the nuns rated the intensity of the subjective experience during the Control and Mystical conditions using a rating scale ranging from 0 (no experience of union) to 5 (most intense experience of union ever felt). This was a rating of how they actually felt during the scan, not how they felt during the original episode (recalled to elicit the Control and Mystical states). So during the scan, the nuns felt equally intense about remembering "union with God" and "union with human." During the Mystical condition, the nuns reported feeling the presence of God, unconditional and infinite love, plenitude, and peace. They also reported feeling unconditional love during the Control condition.
