Figure 14.
Manhattan plot of individual SNP associations with alpha peak frequency at occipital-parietal leads. Manhattan plots also depict the distribution of −log10(p) but are ordered by SNP location on a chromosome, which provides information about the location of any SNPs associated with small p-values. The horizontal line at 7.3 indicates the genome-wide significance level (5E-08). The horizontal line at 5 indicates E-05, which is sometimes used to indicate “suggestive” significance.
