Comparison of beta-band cost efficiency and power correlations with accuracy before and after practice in control subjects. (A) Negative correlations of accuracy with beta-band local cost efficiency (Holms–Bonferroni p < 1.8E-4) before and after practice. (B) Positive (top) and negative (below) correlations of accuracy and mutual information between sensors before (FDR p < 0.0017) and after practice (FDR p < 1.5E-4) in controls only. (C) Positive correlations of accuracy with beta-band power (dark red, Holms–Bonferroni p < 1.8E-4, light red, FDR p < 0.0036). (D) Nodes in which Δaccuracy correlated positively with Δpower among control subjects after practice in the gamma (D₁), and beta (D₂) frequency bands. (E₁) Nodes in which Δaccuracy negatively correlated with Δlocal cost efficiency in control subjects (FDR, p < 0.0037). (E₂) Top and side view of sensors that exhibited a positive correlation between Δaccuracy and ΔMI for controls in the beta band (FDR p < 5.9E-5).
