Post-hoc pairwise comparisons: paired t-tests (2-tailed) assessing differences in bilateral HG cortical thickness values between professional musicians (μ = 2.40 mm), amateurs (μ = 2.41 mm) and non-musicians (μ = 2.32 mm), adjusted for age, sex, whole brain cortical volume and scanner. Comparisons are corrected for multiple comparisons (Bonferroni). *Indicates significance at α = 0.05.
