http://en.wikipedia.org/wiki/Glossolalia 'Glossolalia' is constructed from the Greek word γλωσσολαλία, itself a compound of the words γλῶσσα (glossa), meaning "tongue" or "language" and λαλέω (laleō), "I speak, I talk". The term 'speaking in tongues' is a translation of these two components of the same word.
In 2006, the brains of a group of individuals were scanned while they were speaking in tongues. Activity in the language centers of the brain decreased, while activity in the emotional centers of the brain increased. Activity in the area of control decreased, which corresponds with the reported experience of loss of control. There were no changes in any language areas, suggesting that glossolalia is not associated with usual language function. Other brain wave studies have also found that brain activity alters in glossolalia.

http://www.spiritualjourneyart.com/election-results-for-senator-from-ga-analog-drawings/uncategorized} I started to work on my website today - which is a great embarassment to me at present - and then felt a sudden urge to do a series of analog drawings about the Georgia election results that distressed me so much last night. I started by “dancing it” - just expressing in movement the feeling that came. This was easy — started with plenty of pushing away and fierce grunts! Then some turning away - holding away - but when I placed my right hand on my heart, everything changed and almost reluctantly I began reaching out a bit with my left... The seven analog drawings — quick “free drawings of the feeling” done in soft Ebony pencil on slightly rough paper — follow a similar progression. I’ve scanned them in. (This kind of drawing is often called automatic drawing. It’s a kind of spontaneous gesture of the whole body-mind.)
