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.
