Figure 6: N2 and auditory SR scalp topography and attention effects. (a) Effect of attention on N2 TFP in each subject group (active-passive blocks). (b) Active, passive, and difference voltage maps for N2 at the peak latency of electrode Fz. (c) Effect of attention on SR TFP in each subject group (active-passive blocks). (d) Active, passive, and difference voltage maps for SR averaged from 400 to 900 ms. The error bars in (a) and (c) are one standard error ( ; ).
