Fig 8. Event-related potentials (ERPs) evoked by the intracutaneous electrical stimuli over contralateral sites (T7 and C5) in the sustained spatial attention conditions.

Averages are shown for cued stimuli in the first and the second session (Cue1 and Cue2) and for uncued stimuli in both sessions (Unc1 and Unc2). Results for high intensity stimuli are displayed in the two upper rows while results for the low intensity stimuli are presented in the two lower rows. Results for the pre-post group are presented in the left panel, while results for the post-post2 group are presented in the right panel.
