This review presents the current status of a method for prevention and timely correction of human functional disturbances that was first proposed by Russian neurologist Ya.I. Levin in 1998 and further developed by the authors. The approach is named "Music of the Brain" and is based on musical or music-like stimulation organized in strict accordance with the biopotentials of a patient's brain. Initial studies on the music of the brain approach were analyzed, and its limitations were noted. To enhance the efficiency and usability of the approach, several combinations of music therapy with neurofeedback technique - musical neurofeedback - were developed. Enhanced efficiency of the approach has been shown for correction of functional disturbances during pregnancy and for elimination of stress-induced states in high technology specialists. The use and advantages of musical neurofeedback technology for increasing human cognitive activity, correcting sleep disturbances and treatment of disorders of attention were verified. After further development and testing the approach may be suited for a wide range of therapeutic and rehabilitation procedures in the protection of public health.
The aim of the investigation was to compare efficacy of three variants of musical neurobiocontrol technology, involving transformation of the current values of the patient's EEG oscillators into music-like signals in correcting stress-induced functional state.Materials and Methods. 15 volunteers, being in the stress condition, were subject to three examinations. In the first one the examinees were presented music-like signals, resembling the sounds of a flute by its timbre, which were smoothly varying in pitch and intensity in direct relation to the current amplitude of the spectral component of EEG -EEG oscillator -dominating in the subject. In two other examinations the same transformations of EEG were supplemented by the introduction of musical elements: rhythm and beat. Objective (shifts of EEG-alpha rhythm intensity relative to the background) and subjective (results of all tests before and after the exposure) criteria of efficacy were used in the study.Results. Under the influence of therapeutic procedures the increase of EEG-alpha rhythm intensity against the background was noted, accompanied by the growth of health and mood indicators, reduction of emotional disadaptation degree and the level of stressedness in the examined persons. The most prominent effects were revealed when presented sound signals were structured, especially by introducing 1 Hz rhythm in them.Conclusion. Transformation of the current values of patient's EEG oscillators into music-like signals is supposed to be a perspective way of improving the efficacy of biocontrol procedures in correcting various functional disorders.
Music of the Brain" is based on musical or music-like stimulation organized in close accordance with the biopotentials of a subject's brain. Initial studies of the "Music of the Brain" approach were analyzed and limitations were noted. To enhance the efficiency and usability of the approach, several combinations of music therapy with a neurofeedback technique -musical neurofeedback were developed. Enhanced efficiency of the approach has been shown for the correction of functional disturbances during pregnancy and for elimination of stress-induced states in high technology specialists. The use and advantages of musical neurofeedback technology for increasing human cognitive activity, correcting sleep disturbances, and treatment of disorders of attention were verified. After further development and testing the approach may be suited for a wide range of therapeutic and rehabilitation procedures in the public health arena.
