Influence of COMT and BDNF polymorphisms on LRTCs

(A) Detrended fluctuation analysis (DFA) exponents averaged across parcels for the COMT and BDNF polymorphism groups. Shaded areas represent 95% bootstrapped confidence intervals of group means. Black bar with asterisk denotes the range of frequencies with significant differences between the COMT and BDNF polymorphism groups (univariate ANOVA, with age as covariate, ∗: p < 0.05, controlled for multiple comparisons with cluster-based permutation statistics).

(B) Fractions (P) of parcels with a significant positive or negative difference between COMT and BDNF polymorphism groups in the DFA exponents (Mann–Whitney-U test, p < 0.05), as in Figure 2B.

(C) Cortical areas where significant differences between polymorphism groups in the DFA exponents were found in the θ, β–γ, and α– low-β bands (Mann–Whitney U test, p < 0.05, corrected). Colors and abbreviations as in Figure 2C.
