Alteration of cross-correlation couplings after carrying out of non-medicated rehabilitation course using biofeedback (biofeedback training)
is reflected in the illustration. Before biofeedback training using (a, b pictures) the biggest correlations in couplings
structure were observed between frontalis right temporal derivations in theta-waves frequency range with three isolated
correlation pleiads in right frontalis-central, right cervical and left temporal areas. After 5 sessions of biofeedback training (c, d pictures),
correlation couplings decreased in temporal areas with simultaneous substantial increase of correlation couplings number
in alpha-rhythm frequency range by all derivations.
