A reorganization of the spectral power (SP) of the human brain potentials takes place during listening to music. The characteristic features of the reorganization depend on the type of the musical composition. Listening to classical music (of low and moderate intensity) produces an increase in the SP of the high-frequency EEG (α2, β1, β2, and γ bands)(More)
Human growth hormone (GH) has several central metabolic functions including bone growth in childhood, and its anabolic and lipolytic effects in particular are assumed reasons for the abuse of GH by athletes. Human endogenous GH consists of a main 22 kDa variant and several isoforms. In contrast, recombinant GH consists of only one variant being identical to(More)
Different musical styles and intensities produce characteristic patterns of changes in the correlation of neocortical biopotentials. Classical music of three intensities and rock music of medium and high intensities were shown to produce asymmetry in the pattern of coherence (Coh) of the cortical activity of listeners: intrahemispheric Coh in the right(More)
The recognition of noisy visual images (Arabic numerals) carried out under the conditions of recognition accompanied by classical or rock music of a specified power improves the recognition. When music-accompanied recognition of visual images is carried out, the structure of coherent relations (their number and significance level) observed during(More)
Recognition of noisy pictures of Arabic numerals was accompanied by an increase in EEG coherence in the frontal cortical regions, especially in the left hemisphere, and between the frontal and occipital areas in both left and right hemispheres. Coherence values decreased in the temporo-centro-occipital areas of both hemispheres. A correlation was found(More)
Changes in the EEG depend on the style of accompanying music. Classical music produces more patterns with increased diagonal coherences in the γ frequency band, where two foci of integration are formed at points T 4 and T 6. During listening to rock music, a larger proportion of all changes occurred in the θ-and α1 frequency bands; an integration focus was(More)
Changes in EEG coherence were studied in subjects without special musical education when they were listening to low classic music (below 30 dB). The numbers of significant changes in coherence function in the left and right hemispheres were different. Predominant increase in coherence in the alpha 2, beta 1, and beta 2 frequency ranges was observed in the(More)
The efficiency of the recognition of masked visual images (Arabic numerals) increased when accompanied by classical (62 dB) and rock music (25 dB). These changes were accompanied by increases in the coherence of potentials in the frontal areas seen on recognition without music. Changes in intercenter EEG relationships correlated with the formation a(More)
The effects of music with specific intensity on the latencies of the left or right hand motor responses to visual stimuli have been studied. When the latency of the initial motor response is more than 400 ms, the music accompaniment decreases the latency of the motor response of the left hand. It is supposed that the decrease in the mean latency of the left(More)
