a Scatter plot between mean PF estimates (horizontal axis) and delayed correlation (vertical axis) on the four visual experiments fMRI data. A \(p<0.001\) was obtained with a Pearson’s correlation coefficient \(\rho =0.70\). The black line is the result of a linear fit. Slope and offset of the linear fit were 1.10 and 0.25 respectively. b Scatter plot between average PF estimates (horizontal axis) and stationary AR coefficients (vertical axis). The resulting Pearson’s correlation coefficient \(\rho \) was 0.94, with a \(p<0.001\). The black line is the result of a linear fit, with slope and offset 1.2 and \(-0.004\) respectively
