![]() ![]() In conclusion, neural resynchronization was met with both personalized theta and beta BB, but no different mental conditions seemed to be achieved.ĮEG beta binaural beats brain entrainment theta.Ĭopyright © 2021 Corona-González, Alonso-Valerdi and Ibarra-Zarate. ![]() In addition, relative power analysis (theta BB/resting state) revealed alpha band desynchronization in the parieto-occipital region when volunteers listened to theta BB, suggesting that participants felt uncomfortable. However, no significant differences were found between theta and beta BB sessions when it was expected to achieve different brain entrainments, since theta and beta BB induce relaxation and readiness, respectively. Studies using electroencephalography (EEG) have shown that binaural beats give rise to neural entrainment over multiple frequency ranges including theta (47 Hz), alpha (812 Hz), beta (1330 Hz), and gamma (> 30 Hz) bands (Ala et al., 2018 Beauchene et al., 2016 Becher et al., 2015 Draganova et al. This power change seems to be related to auditory perception and sound location. Results showed larger absolute power differences for both BB stimulation sessions than resting state on bilateral temporal and parietal regions. Beta frequency binaural-beat audio signals were utilized to investigate facilitation of human performance on two memory tasks and two memory related tasks. EEG analysis was based on the comparison of power spectral density among three mental conditions: (1) theta BB stimulation, (2) beta BB stimulation, and (3) resting state. To achieve this aim, 20 healthy volunteers were stimulated with their personalized theta and beta BB for 20 min and their EEG signals were collected with 22 channels. ![]() The adjustable frequencies were estimated for each participant in accordance with their heart rate by applying the Brain-Body Coupling Theorem postulated by Klimesch. Personalized BB consisted of pure tones with a carrier tone of 500 Hz in the left ear together with an adjustable frequency in the right ear that was defined for theta BB (since f c for theta EEG band was 4.60 Hz ± 0.70 SD) and beta BB (since f c for beta EEG band was 18.42 Hz ± 2.82 SD). The aim of this research was to investigate whether personalized BB (specifically those within theta and beta EEG bands) improve brain entrainment. Deep Sleep Meditation 2 Hz Binaural Beats (20 Min) Binaural beats royalty free meditation music (2 Hz deep sleep Delta frequency, 20 min) with ethereal ambient feel for deep sleep relaxation video, guided meditation, dreamy film background, zen ambiance, and commercial business use. This auditory stimulation has been widely used to module brain rhythms and thus inducing the mental condition associated with the EEG bandwidth in use. Binaural beats (BB) consist of two slightly distinct auditory frequencies (one in each ear), which are differentiated with clinical electroencephalographic (EEG) bandwidths, namely, delta, theta, alpha, beta, or gamma. ![]()
