“Speaking in tongues,” or “Glossolalia” as it is referred to by academics, has been around for thousands of years, and is referenced by both the Hebrew Scriptures and the New Testament. Although the individual is seemingly speaking in an incomprehensible language, it still seems to have tremendous personal meaning. Now in perhaps the first study of its kind, researchers from the University of Pennsylvania School of Medicine have conducted a study on the brain patterns of those engaged in Glossolalia – they are attempting to explain what happens physiologically to the brain of someone while speaking in tongues – and their findings make for interesting reading.
This is because they have discovered that the language centre of the brain is not under the control of subjects who speak in tongues. There was decreased activity in the frontal lobes, an area of the brain associated with being in control of one’s self. Radiology investigators observed increased or decreased brain activity by measuring cerebral blood flow with SPECT (Single Photon Emission Computed Tomography) imaging while the subjects spoke in tongues. They then compared the imaging to what happened when the same subjects sang gospel music.
“We noticed a number of changes that occurred functionally in the brain,” commented Principal Investigator Andrew Newberg, MD, Associate Professor of Radiology, Psychiatry, and Religious Studies, and Director for the Center for Spirituality and the Mind, at Penn. “Our finding of decreased activity in the frontal lobes during the practice of speaking in tongues is fascinating because these subjects truly believe that the spirit of God is moving through them and controlling them to speak. Our brain imaging research shows us that these subjects are not in control of the usual language centers during this activity, which is consistent with their description of a lack of intentional control while speaking in tongues.”
Newberg went on to explain, “These findings could be interpreted as the subject’s sense of self being taken over by something else. We, scientifically, assume it’s being taken over by another part of the brain, but we couldn’t see, in this imaging study, where this took place. We believe this is the first scientific imaging study evaluating changes in cerebral activity -- looking at what actually happens to the brain -- when someone is speaking in tongues. This study also showed a number of other changes in the brain, including those areas involved in emotions and establishing our sense of self.”
