(A) Motor performance-related (abrupt condition) modulations of resting state connectivity across the full sample of 20–75-year-old participants. Values represent correlations between performance and both intranetwork (diagonal) and internetwork (off-diagonal) connectivity. Negative values indicate increased connectivity was associated with decreased performance (accuracy). Tests of statistical significance were based on comparisons of the correlation coefficients to a correlation of 0 and corrected for multiple comparisons with a false discovery rate (FDR) threshold set to 0.05. Corrected p-value threshold was 0.0011. • = P(FDR) < 0.05 (below diagonal); o = P(uncorrected) < 0.05 (above the diagonal). (B) Accuracy on the abrupt condition plotted as a function of mean internetwork connectivity. Black and red trajectories depict linear fit and corresponding 95% prediction intervals, respectively.
