Speaking in tongues, now, with brain imaging.

But what does it mean?

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....

“The amazing thing was how the images supported people’s interpretation of what was happening,” said Dr. Andrew B. Newberg.... “The way they describe it, and what they believe, is that God is talking through them,” he said....

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.

I'd like a little more analysis and contrasting opinion in this article, which reads too much like a press release from Dr. Newberg. For example: Are these brain patterns similar to dreaming?
