Manhattan plot displaying genome-wide meta-analysis association results for interhemispheric low theta coherence (P3-O1—P4-O2)Genome-wide association results for low theta EEG coherence in the genome-wide meta-analysis of individuals of European and African ancestry. Y axis denotes the −log10 (P-value) for association. X axis is the physical position of the SNPs across the genome. Note: Red line indicates the threshold of genome-wide significance (P<5 × 10–8).
