Increasing attention has been paid to the nonlinear functional activity of human brain regions. This paper extends Chatterjee’s correlation coefficient (CCC) method to model nonlinear relationships in brain functional networks explicitly. Specifically, the reliability and effectiveness comparisons between CCC and the Pearson correlation coefficient (PCC) are demonstrated using simulated data and two real resting-state functional magnetic resonance imaging (rs-fMRI) datasets: The Midnight Scan…
