The extensive exploration of the correlation between electroencephalogram (EEG) and heart rate variability (HRV) has yielded inconsistent outcomes, largely attributable to variations in the tasks employed in the studies. The direct relationship between EEG and HRV is further complicated by alpha power, which is susceptible to influences such as mental fatigue and sleepiness. This research endeavors to examine the brain-heart interplay typically observed during periods of music listening and rest. In an effort to mitigate the indirect effects of mental states on alpha power, subjective fatigue and sleepiness were measured during rest, while emotional valence and arousal were evaluated during music listening. Partial correlation analyses unveiled positive associations between occipital alpha2 power (10-12 Hz) and nHF, an indicator of parasympathetic activity, under both music and rest conditions. These findings underscore brain-heart interactions that persist even after the effects of other variables have been accounted for.
脑电图（EEG）和心率变异性（HRV）之间相关性的广泛探索产生了不一致的结果，这主要归因于研究中使用的任务变化。EEG 和 HRV 之间的直接关系进一步受到阿尔法功率的影响，阿尔法功率容易受到精神疲劳和困倦等因素的影响。本研究旨在检查音乐聆听和休息期间通常观察到的大脑-心脏相互作用。为了减轻精神状态对阿尔法功率的间接影响，在休息时测量主观疲劳和困倦，而在音乐聆听时评估情绪效价和唤醒度。偏相关分析显示，在音乐和休息两种情况下，枕部阿尔法 2 功率（10-12Hz）与 nHF（副交感活动的指标）之间存在正相关。这些发现强调了即使在考虑了其他变量的影响后，大脑-心脏相互作用仍然存在。
