Figure Lengend Snippet: Preprocessing and data quality. ( a ) Average response over trials in the picture naming task (session 1 of dataset 1), left: sub-05, right: all participants. ( b ) Average response over trials in the auditory task of dataset 2, left: sub-10, right: all participants. ( c ) Sensor layout of the hydrocel geodesic system (256 channels, EGI) with the removed channels (blue and red) when performing preprocessing by Automagic. ( d ) Quality metrics across all participants and trials in dataset 1 and dataset 2, (top/left): number of interpolated channels per epoch, (top/right): mean absolute voltage per epoch, (bottom/left): percentage of channels for which the standard deviation across time exceeds 15 uV, (bottom/right): percentage of time points where the standard deviation across channels exceeds 15 uV.
