"Brain research is beginning to produce concrete evidence for something that Buddhist practitioners of meditation have maintained for centuries: Mental discipline and meditative practice can change the workings of the brain and allow people to achieve different levels of awareness...over the past few years, researchers at the University of Wisconsin working with Tibetan monks have been able to translate those mental experiences into the scientific language of high-frequency gamma waves and brain synchrony, or coordination. And they have pinpointed the left prefrontal cortex, an area just behind the left forehead, as the place where brain activity associated with meditation is especially intense..."What we found is that the longtime practitioners showed brain activation on a scale we have never seen before"...especially interested in measuring gamma waves, some of the highest-frequency and most important electrical brain impulses...the electrodes picked up much greater activation of fast-moving and unusually powerful gamma waves in the monks, and found that the movement of the waves through the brain was far better organized and coordinated...some of the monks produced gamma wave activity more powerful than any previously reported in a healthy person..."
