MZ and DZ twin correlations are denoted r(MZ) and r(DZ), respectively. Exponent lists the average DFA exponent ± SD. The r indicates the phenotypic correlation between power and DFA exponents as given by maximum likelihood estimations. The rightmost three columns indicate number of subjects (n) that pass the signal-to-noise ratio criterion at a given electrode and the resulting heritability and phenotypic correlation from this subset of subjects. Significance levels as derived from likelihood ratio tests are as follows: *p < 0.01; **p < 0.001.
