Higuchi fractal dimension: An efficient approach to detection of brain entrainment to theta binaural beats

摘要: Abstract Binaural beats (BBs) are two pure tones with a small frequency difference (i.e., beat) separately presented to each ear. They cause the beat perception in brain. BBs used both clinical and basic science applications. Studies BB literature have mainly focused on linear analysis of brain signals. Even though these approaches produced promising findings, there may still be some facets left considered, which cannot studied by measures. entrain generate synchronous responses. Previous studies proved that increasing synchronicity reduced its complexity measured fractal dimension (FD). In this study, Higuchi (HFD) was test whether: 1) stimulation decreases electroencephalogram (EEG) complexity, 2) HFD is reliable alternative common counterpart relative power band lies) terms entrainment detection. Results revealed 3-min significantly decreased temporal parietal lobes, about half time required probe any changes EEG power. Moreover, significant negative correlation between regions. comparison power, mostly higher classification accuracies areas under empirical receiver operating characteristic (ROC) curve lobes. Our findings suggest can replacement for detection response classification.
