PA domains containing significant PAC clusters in men. Standard PA domain boundaries marked by black dotted lines. Only clusters considered for analysis were those falling within one of the standard PA domains represented on the comodulograms analyzed in this study, which include the delta-gamma, theta-gamma, alpha-gamma, delta-beta, theta-beta, alpha-beta, delta-alpha, and theta-alpha domains. These domain boundaries are based on standard EEG frequency bands of delta (0.1–3 Hz), theta (3–8 Hz), alpha (8–13 Hz), beta (13–28 Hz), and gamma (28–50 Hz). Faded regions of the comodulogram have been excluded from cluster analysis.
