Grand average across participants frontal (Fz) event-related potentials in the LT oddball paradigm for the first (above) and second (below) blocks to nontarget stimulus (standards), target stimulus (deviants), and the difference waves data, that were obtained by subtracting the standard stimulus ERP from that of the deviant stimulus. Vertical dotted lines show the beginning and end of the stimulus. Evoked potential components are identified on the first block. The data were referenced to the nose electrode.
