LD score regression for Hapmap 3 annotated SNPs (NSNP> 819k) was carried out for SNP effects from the meta‐analysis. Heritability estimates (ranging from 0.11 to 0.27; Supporting Information Figure S5) were lower than estimates from twin and family studies of EEG power (ranging from 0.45 to 0.9; e.g., see Smit et al., 2005), but are in line with the GCTA random‐effects modeling on common SNPs for the same EEG measures (Malone et al., 2014), as well as other neuropsychiatric and behavioral traits.
