Richard Davidson, Director of the Keck Laboratory for Functional Brain Imaging and Behavior at the University of Wisconsin has recently been involved in a series of studies that ask how meditation can influence our emotions and the way we react to real-life-experiences. His research has shown that there is a remarkably high level of gamma activity in experienced meditators. Gamma waves are generally understood to indicate that higher cognitive functions are taking place. You can read more about this research in the current issue of Yoga International – Brain and Meditation.
