Figure 2From: Increased performance uncertainty in children with ADHD? - Elevated post-imperative negative variation (PINV) over the ventrolateral prefrontal cortexPINV topography: ADHD versus healthy control children. Comparison of the PINV topographies 2000 to 3000 ms after the imperative stimulus S2 in ADHD children versus healthy control children. The activation over the prefrontal cortex is displayed by different shades of grey. Current sinks (negative potential shifts) are presented striped and current sources (positive potential shifts) without stripes with a scale ranging from -6.5 μV to +5 μV.Back to article page
