Abstract
In distinction, higher power in the gamma band has been found in advanced Buddhist meditators across differing meditation practices. We used exact Low Resolution Electromagnetic Tomography (eLORETA) to compare experienced (mean 4 years’ experience) and advanced (mean 30 years’ experience) Australian meditators from the Satyananda Yoga tradition on two meditation practices and a mental calculation (counting) condition. The advanced group had significantly higher current source density (CSD) in the high frequencies predominantly in the right temporal lobes, insula and inferior frontal gyrus.
