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. A coherence of potentials was decreased in EEG of frontal cortex. Music decreasing of making-decision time enhanced left-sided EEG asymmetry The intrahemispheric and the interhemispheric coherences of frontal cortex were increased during the decision of MLT accompanied by music. Using of musical accompaniment 85 dB produced a right-side asymmetry in EEG and formed a focus of coherent connections in EEG of temporal area of a right hemisphere.
在古典音乐伴奏（强度为35和65分贝）期间，数学逻辑任务（MLT）的决策时间缩短。85分贝的音乐对MLT的决策过程没有影响。无音乐伴奏的决策导致枕叶区域脑电图中β1、β2、γ频率范围内的相干函数值增加，且以左侧半球为主。额叶皮质脑电图中的电位相干性降低。音乐缩短决策时间增强了脑电图的左侧不对称性。在音乐伴奏的MLT决策过程中，额叶皮质的半球内和半球间相干性增加。使用85分贝的音乐伴奏在脑电图中产生了右侧不对称，并在右侧半球颞叶区域的脑电图中形成了相干连接焦点。
