The neuroscience of speaking in tongues

Amazing. I've spoken in tongues since high school, when I prayed for the "baptism of the Holy Spirit" as described in Acts one night. I still speak in tongues, or rather pray in tongues, regularly. Mostly, I do this because I believe speaking in tongues is a method of spiritual communion with God, who is also Spirit.

From yesterday's New York Times:

Researchers at the University of Pennsylvania took brain images of five women while they spoke in tongues and found that their frontal lobes — the thinking, willful part of the brain through which people control what they do — were relatively quiet, as were the language centers. The regions involved in maintaining self-consciousness were active. The women were not in blind trances, and it was unclear which region was driving the behavior.
...
In the study, the researchers used imaging techniques to track changes in blood flow in each woman’s brain in two conditions, once as she sang a gospel song and again while speaking in tongues. By comparing the patterns created by these two emotional, devotional activities, the researchers could pinpoint blood-flow peaks and valleys unique to speaking in tongues.

The new findings contrasted sharply with images taken of other spiritually inspired mental states like meditation, which is often a highly focused mental exercise, activating the frontal lobes.

The scans also showed a dip in the activity of a region called the left caudate. “The findings from the frontal lobes are very clear, and make sense, but the caudate is usually active when you have positive affect, pleasure, positive emotions,” said Dr. James A. Coan, a psychologist at the University of Virginia. “So it’s not so clear what that finding says” about speaking in tongues.

The caudate area is also involved in motor and emotional control, Dr. Newberg said, so it may be that practitioners, while mindful of their circumstances, nonetheless cede some control over their bodies and emotions.
