(a) Grand average ERPs (referenced to average mastoids) to attended and unattended standard laser stimuli at 8 electrode sites F1, F2, C1, C2, P1, P2, O1, and O2. ERPs elicited to the Off and On laser conditions are superimposed with unattended stimuli shown in the left-hand panel and attended stimuli shown in the right-hand panel. Left and Right stimulus locations are shown. Peak amplitudes: P1 = 131 ms; N1 = 159 ms; P2 = 222 ms. (b) Difference waves of ERPs from panel 2a, attended minus unattended standard laser stimuli for Off and On conditions for left and right stimulus locations at eight electrode sites. (c) Grand average ERPs to attended and unattended infrequent deviant stimuli. Please see panel 2a caption for figure details. P3 peak amplitude = 390 ms.
