Fig. 3.

Stimulus-locked waveforms (current source density) and topographic maps (for Nogo trials only) for activation in the RIDE S-Cluster. Figure shows A) P1_RIDE/N1 _RIDE, B) P2 _RIDE and C) N2 _RIDE component for Go and Nogo trials, for both time points (T1 = baseline testing, T2 = testing after 8 weeks of intervention/waiting list status) and for all three experimental groups (MPH = patients treated with methylphenidate; NF = patients treated with neurofeedback; WLC = patients included as waiting list controls). Point 0 denotes Go/Nogo stimulus onset. In the topographic maps (shown only for Nogo trials), blue denotes negative deflections whereas red denotes positive ones.
