Since I am one of the 4 authors of the the glossolalia paper, and the coauthor with Newberg of "Why We Believe What We Believe," let me add some notes to this intriguing discussion. First, speaking in tongues is essentially an altered state of consciousness in which the person deliberately changes the overall neural functioning of his or her brain. Chanting, drumming, and shamanic trance states probably would show similar brain states, with decreases in frontal lobes and unusual changes in other areas. Interestingly, in Newberg's other brainscan studies, nuns praying and Buddhists meditating had similar altered brain patterns to each other, but were almost the opposite of the Pentecostals, who never lost sense of themselves and thus do not feel "at one" with the universe or God. Instead they stay present, in dialogue with the Holy Spirit. Is God just an imaginative construct in the brain? Obviously yes (even if God does exist, the brain has to conceive of God to experience it). But what is most interesting about intense meditations is that they can permanently change the neural structure of the brain. All of Newberg's subjects, including the nuns, Buddhists, and one atheist who attempted to pray to God (see the book, "Why We Believe What We Believe" for a full description of all of these studies) had assymetric activity in the thalamus when they weren't even meditating. The longer you focus on any concept, other parts of the brain will respond as if that idea was objectively real. Focus on peace, you become more peaceful; focus on your anger, and your anger will feel justified and real. If you believe in God, God eventually becomes real. So be careful about what you believe!
PS: ADD is a permanent neural dysfunction where frontal lobe activity is disrupted
