Left column Maps of $r_{\text{UG}}$ for two volunteers who had regions with modified response shapes and discrepancies between GLM and UNBIASED results. White arrows point to clusters of $r_{\text{UG}}>0$ (better quality of fit in UNBIASED). Middle columns GLM (left) and UNBIASED (right) activation and reliability maps in radiological convention (25 % transparency). Right column Plots of the mean (blue line) and standard deviation (blue shaded area) time courses in cubic ROIs (white boxes centered at the clusters with $r_{\text{UG}}>0$). Green lines represent the GLM model regressor and black lines the stimulus timing
