Does Double Biofeedback Affect Functional Hemispheric Asymmetry and Activity? A Pilot Study

In the current pilot study, we attempt to find out how double neurofeedback influences functional hemispheric asymmetry and activity. We examined 30 healthy participants (8 males; 22 females, mean age = 29; SD 8). To measure activity, used computer laterometry in "two-source" lead-lag dichotic paradigm. Double biofeedback included 8 min of EEG oscillation recording with five minutes basic mode. During mode, amplitude oscillator gets transformed into feedback sounds while alpha is modulate intensity light signals. did not directly influence itself but accelerated individual sound perception characteristics during listening preceding effect Further research needed investigate training on brain activity asymmetry, taking account participants' age, gender, motivation.
