[Influence of music on a decision of mathematical logic tasks].

Accompaniment of a decision of mathematical logical tasks by music (different style and power) influenced on the time of the decision. Classical music 35 and 65 dB and roc-music 65 and 85 dB decreased the time of the decision. More powerful classical music (85 dB) did not effect like that.

[Decision of mathematical logical tasks in sensory enriched environment (classical music)].

The time of a decision of mathematical logical tasks (MLT) was decreased during classical musical accompaniment (power 35 and 65 dB). Music 85 dB did not influence on the process of decision of MLT. Decision without the musical accompaniment led to increasing of coherent function values in beta1, beta2, gamma frequency ranges in EEG of occipital areas with prevalence in a left hemisphere.

[Effect of music on the latency recognition of even and odd numbers].

Studied influence of music of certain intensity on latency recognition of even and odd numbers with participation of the left and right hand accordingly. Music accompaniment decreased the latency recognition more pronounced with participation of the left hand that, apparently, is connected with activated influence of music on the right hemisphere at the people who are not professional musicians. Increase of efficiency of recognition in music accompaniment is considered as realisation of a principle of a dominant.

[EEG in mathematical logical problem solving].

The model of mathematical logic tasks was developed at which decision there was a value coherence in delta-range raised. In low-frequency ranges (delta, theta, and alpha) a coherence of potentials of frontal cortex were increased. In high-frequency ranges (beta1, beta2, gamma) in frontal cortex coherence was decreased, and its increasing in central, parietal, temporal, and occipital areas with prevalence in the left hemisphere.

Influence of music with different volumes and styles on recognition activity in humans.

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 dominant at the behavioral level.
