Fig. 2. Means ± SE of asymmetric activation during baseline for subjects in the Meditation group and Control group during Time 1 (before random assignment, before treatment began) and Time 3. The ordinate is an asymmetric metric that represents right minus left log-transformed power density from the C4/C3 electrode sites. This is a standard index of asymmetric activation (20). Higher numbers on this indicate greater left-sided activation.
