Increased Gamma Brainwave Amplitude Compared to Control in Three Different Meditation Traditions

Fig 1

The continuum of attentional engagement, from the high level of focused attention to more diffuse“open monitoring” or “open awareness” meditation.

The three meditation traditions we chose to include in our study can be placed along this continuum, each corresponding to a different focus of attention. Himalayan Yoga tradition uses a mantra to maintain the attentional focus, Vipassana tradition is primarily an open monitoring practice but the specific form assayed (as taught by S. N. Goenka) incorporates loose focus on the somatosensory awareness aspect and the Shoonya practice as taught in the Isha Yoga tradition is an open awareness meditation practice with no specific object to focus on.
