STUDY EXAMINES BRAINS OF THOSE SPEAKING IN TONGUES

From the Nightline story: "When they are actually engaged in this whole very intense spiritual practice … their frontal lobes tend to go down in activity. … It is very consistent with the kind of experience they have, because they say that they're not in charge. [They say] it's the voice of God, it's the spirit of God that is moving through them," said Newberg. "Whatever is coming out of their mouth is not what they are purposefully or willfully trying to do. And that's in fairly stark contrast to the people who are — like the Buddhist and Franciscan nuns — in prayer, because they are very intensely focused and in those individuals the frontal lobes actually increase activity.”
