Grand-averaged waveforms at centro-parietal and frontal sites at which the LPP was scored, shown separately for each group and condition. Note. Stimulus onset occurred at 0 ms, task instruction occurred at 1,000 ms. Dashed boxes indicate the time-windows in which the LPP was analyzed. On the y-axis, positive amplitude is plotted down. CEC = combat exposed controls; PTSD = posttraumatic stress disorder.
