From: MAOA variants differ in oscillatory EEG & ECG activities in response to aggression-inducing stimuli
Comparisons of the EEG γ response at F8 across MAOA genotypes. (a) Power spectral density of the γ wave at F8. The panels represent power spectral density by time (10–117.75 s) and frequency (30–90 Hz) intervals across MAOA genotypes. At the bottom of each panel, the first arrow represents the start of the NS (19 s), and the second arrow represents the start of S (stimulus, 28 s). (b,c) represent the MSE value of the γ wave at F8 during NS and S between MAOA genotypes in men and women, respectively. (d,e) represent the relative power value of the γ wave at F8 during NS and S between MAOA genotypes in men and women, respectively. All values are represented as the means ± SEM. The sample size for EEG measurement was 84, including 36 men (21 for 3.5R/Y, 15 for 4.5R/Y) and 48 women (23 for 3.5R/3.5R, 5 for 4.5R/4.5R, and 20 for the heterozygous group). *, **, and *** above the horizontal lines indicate statistically significant differences between MAOA genotypes at p < 0.05, 0.01, and 0.001, respectively, by repeated measures of two-way ANOVA with Bonferroni post hoc test; * and ** above the graph bars indicate statistically significant differences between NS and S at p < 0.05 and 0.01, respectively, by repeated measures of two-way ANOVA with Bonferroni post hoc test.
