From a new brain imaging study at the University of Pennsylvania School of Medicine, SPECT scans were taken of subjects while worshiping versus speaking in tongues. The speaking in tongue images primarily show a decrease of brain activity in the frontal lobes, which is what normally makes us feel as if we're in control. There was also a decrease in activity in the left basal ganglia, which is involved with focusing attention and emotional responses. Finally, the thalamus activity increased during speaking in tongues which supports it is an active state of the brain.
