Pairwise GLM fits between RT, baseline pupil diameter, evoked pupil dilation and magnitude of prestimulus EEG alpha.

<p>Shown are linear (green) and quadratic (purple) GLM fit coefficient estimates () between the four measurements: RT, pre-PD, post-PD and pre-EEG_α. For each pairwise GLM fit, measurement label on the top is the response variable, while measurement on the bottom is the predictor variable. Standard error bars are across subjects (N = 14). Significant linear or quadratic relationships (p<0.01, corrected) are denoted by double asterisks. Note that we obtained no results with 0.01
