Figure 4

Grand-averaged ERPs elicited in response to peripheral auditory S2 nontarget stimuli in the 500 ms following stimulus onset (relative to a 100 ms pre-stimulus baseline), at midline electrodes Fz, Cz and Pz. ERPs to stimuli presented on the cued side (solid line) or uncued side (dashed lines) are shown separately for the Covert Attention task (left panel) and the Saccade task (middle panel). The corresponding difference waveforms, obtained by subtracting the ERPs elicited by stimuli presented at uncued locations from ERPs elicited by stimuli presented at cued locations, are shown in the right panel, with solid versus dashed lines now indicating the Covert Attention and Saccade tasks, respectively.
