Correlation between fast alpha (12–15 Hz) ICoh and meditation expertise. Individual difference ICoh values are presented (meditation minus rest); FAM, OMM and LKM pooled together for each individual difference ICoh value. Y-axis—non-dimensional ICoh difference values. The meditation-related inter-hemispheric linear increase of fast alpha ICoh as a function of meditation expertise is depicted on the left for right frontal (F4, F6)—left parietal (P3, P5) electrode pairs. The lack of correlation between meditation-related intra-hemispheric modulation of fast alpha ICoh as a function of meditation expertise is shown on the right.
