Abstract

Introduction: Music is known to impact attentional state without conscious awareness. Listening to music encourages the brain to secrete neurotransmitters improving cognition and emotion.

Aim of work: Analysis of QEEG band width while listening to two music types, identifying different cortical areas activated and which genre has a similar effect to relaxed EEG.

Methods: This is a cross-section interventional analytic study including 76 normal subjects, 55 of them are females (72.37%). Participants listened to 10 min of a single audio track during EEG recording, consisting of (1 min of silence, 3 min of Egyptian folk music, 3 min of silence, then 3 min of Egyptian instrumental classic music (without any lyrics). We analyzed QEEG bands at each brain region during different tracks. The power ratio index (PRI) was calculated for each region, and then the interhemispheric difference was compared.

Results: The participants' ages ranged from 15 to 26 with a mean 16.73 ± 2.37 years. PRI showed a significant increase in the frontal and occipital regions during listening to folk music compared to the silent epoch, where p < 0.001 and p = 0.023, respectively. In the frontal and temporal regions, the classic music epoch evoked the highest PRI interhemispheric difference compared to the folk music epoch, where p = 0.004 and p < 0.001, respectively.

Conclusion: Egyptian folk music has significantly slowed the brain rhythm, particularly in the frontal region, compared to classic music, supporting the hypothesis of a momentary reduction of cognitive capacities by the noise. Classic music was evidently associated with a relaxed state EEG.

音乐的力量：对脑电图信号的影响。

导读：众所周知，音乐可以在无意识的情况下影响注意力状态。听音乐可以促进大脑分泌神经递质，改善认知和情绪。工作目的：分析听两种类型音乐时QEEG的频带宽度，识别不同的皮层区域被激活，以及哪种类型的音乐与放松时的EEG效果相似。方法：对76例正常受试者进行横断面介入分析研究，其中女性55例（72.37%）。在脑电图记录过程中，参与者听了10分钟的单一音轨，包括(1分钟的沉默，3分钟的埃及民间音乐，3分钟的沉默，然后3分钟的埃及器乐古典音乐（没有任何歌词）。我们分析了不同轨迹下各脑区QEEG波段。计算各区域的功率比指数（PRI），比较各区域的脑间差异。结果：参与者年龄15 ~ 26岁，平均年龄16.73±2.37岁。结论：与古典音乐相比，埃及民间音乐显著减缓了大脑节奏，尤其是在额叶区域，这支持了噪音会导致认知能力瞬间降低的假设。古典音乐与放松状态的脑电图明显相关。

期刊介绍： Psychological Research/Psychologische Forschung publishes articles that contribute to a basic understanding of human perception, attention, memory, and action. The Journal is devoted to the dissemination of knowledge based on firm experimental ground, but not to particular approaches or schools of thought. Theoretical and historical papers are welcome to the extent that they serve this general purpose; papers of an applied nature are acceptable if they contribute to basic understanding or serve to bridge the often felt gap between basic and applied research in the field covered by the Journal.
