Data on the heritability of EEG frequencies are quite compelling. The largest twin study estimates the heritability of theta and alpha power to be 0.89 and beta to be 0.86 (van Beijsterveldt and Boomsma, 1994; van Beijsterveldt et al., 1996); these heritability estimates are higher than those for AUDs and other psychiatric diagnoses. Heritability estimates for EEG coherence range between 0.5 and 0.7 (Stassen et al., 1988; van Beijsterveldt and Boomsma, 1994; van Baal et al., 1998; van Beijsterveldt et al., 1998; Chorlian et al., 2007).
