Abstract:

17 volunteers (average age of 20,3 + 1,3 years) underwent training featuring biofeedback procedure to voluntarily increase the power of the beta-2 frequencies in the frontal lobe of one of the hemispheres. Over 12 sessions, the efficiency of training was 76.5% for the right hemisphere (RHS) and 52.9% for the left hemisphere (LHS). Dispersion analysis has demonstrated that specific features of interhemispheric relations on frequencies up to 20 Hz reflect the forming of a functional state optimal for a specific type of cognitive activity while the specific features of the activity itself manifest themselves on higher frequencies. Depending on the biofeedback training scenario conditions, successful control was present in parallel increasing of spectral power and the dominance of the hemisphere in training (the left one for LHS, and the right one for RHS), which is, in fact, relevant not only to the lobes in training but also for other lobes of the hemisphere in training. The presence of partial dominance within the frontal and the lateral lobes caused a decrease in the efficiency of control even when co-oriented changes in EEG spectral power is present.

Nota:

Training di biofeedback per aumentare volontariamente la potenza delle frequenze beta-2 nel lobo frontale di uno degli emisferi, l'analisi della dispersione ha dimostrato che le caratteristiche specifiche delle relazioni interemisferiche su frequenze fino a 20 Hz riflettono la formazione di uno stato funzionale ottimale per un tipo specifico di attività cognitiva.
