Comparative EEG Tracings (IMAGE) Maharishi International University Caption These raw EEG tracings during eyes-closed rest (left) and Transcendental Meditation (right) represent 18 tracings over 6 seconds. The top tracings are from frontal sensors; the middle tracings are from central sensors; the bottom tracings are from parietal and occipital sensors (back). Note the high-density alpha activity in posterior leads during eyes-closed rest, and the global alpha bursts across all brain areas during Transcendental Meditation practice.
