Figure 5
Linear associations between theta (4–7 Hz) ICoh of the medial frontal network (presented as individual difference values, meditation minus rest) and meditation expertise. Upper panel: Graphical maps indicating relevant electrodes where the correlations between theta ICoh and meditation expertise were significant (red circles and connections). Lower panel: Linear increase of theta ICoh as a function of meditation expertise. Positive ICoh difference values reflect meditation-related increase. The linear increase of theta ICoh for FCz-guided left parieto-occipital pairs as a function of meditation expertise is demonstrated for FAM (left); the linear increase of theta ICoh for FCz-guided right frontal pairs as a function of meditation expertise is demonstrated for LKM (right). Y-axis presents non-dimensional ICoh difference values.
