The relationship of visual P3a and P3b to age and neuropsychological performance was investigated in 26 healthy children (6.8–15.8 years) and 129 adult volunteers (20.0–88.8 years).Within the sample of children, an effect of age on midline topography was observed, with higher frontal amplitudes in the youngest compared to the oldest children. Increasing age was associated with lower P3a and P3b am
