Evaluation of the correlation among the activities of various organs is an important research area in physiology. In this paper, we analyzed the correlation between the brain and skin reactions in response to various auditory stimuli. We played three different music (relaxing, pop, and rock music) to eleven subjects (4 M and 7 F, 18–22 years old) and accordingly analyzed the changes in the complexity of Electroencephalogram (EEG) and Galvanic Skin Response (GSR) signals by calculating their fractal exponent and sample entropy. A strong correlation was observed among the alterations of the complexity of GSR and EEG signals in the case of fractal dimension (r = 0.9971) and also sample entropy (r = 0.8120), which indicates the correlation between the activities of skin and brain. This analysis method could be further applied to investigate the correlation among the activities of the brain and other organs of the human body.

大脑和皮肤对不同类型音乐的反应之间的相关性分析

评价各器官活动之间的相关性是生理学的一个重要研究领域。在本文中，我们分析了大脑和皮肤对各种听觉刺激的反应之间的相关性。我们为 11 名受试者（4 M 和 7 F，18-22 岁）播放了三种不同的音乐（放松、流行和摇滚音乐），并相应地分析了脑电图 (EEG) 和皮肤电反应 (GSR) 复杂性的变化通过计算它们的分形指数和样本熵来计算信号。在分形维数的情况下，GSR 和 EEG 信号的复杂性变化之间存在很强的相关性（r = 0.9971) 以及样本熵 (r = 0.8120)，这表明皮肤和大脑活动之间的相关性。这种分析方法可以进一步应用于研究大脑活动与人体其他器官之间的相关性。
