Figure 2From: Controlled evaluation of a neurofeedback training of slow cortical potentials in children with Attention Deficit/Hyperactivity Disorder (ADHD)Changes of mean amplitudes between beginning and end of the training. Differences of the mean amplitudes between the beginning (double session 2–3) and the end (double-session 13–14) of the training during negativity or positivity trials in feedback and transfer conditions are represented in Figure 2.
