Concerning the use of audio-visual stimulation (AVS) as a component of neurofeedback therapy for neuropsychiatric disorders we propose to evaluate its effect onto the brain networks interaction. We performed fMRI before and after the AVS. fMRI exams showed considerable increase of the volumes of activation after the AVS and almost complete extinction of the DMN deactivation. RS fMRI showed functional connectivity changes after the AVS (connectivity disruption in visual network, DMN frequency shift). Volume of activation increase and functional connectivity changes could be the marker for prolonged effect of AVS brain stimulation.
