Figure 2

Stimulus-locked waveforms (current source density) and topographic maps for the N2 and P3 component, depicted for Go and Nogo trials, both experimental groups (NF = neurofeedback, WL = waiting list controls) and both time points at electrodes Cz and FCz.

Point 0 denotes Go/Nogo stimulus onset. In the Nogo-topographic maps blue denotes negative deflections whereas red reflects positive ones. The sLORETA plot shows the pre-post difference in Nogo-P3 amplitudes within the ADHD group. Colours denote t-values corrected using randomization tests.
