In the current study we used electroencephalography (EEG) to investigate the relation between musical tempo perception and the oscillatory activity in specific brain regions, and the scalp EEG networks in the theta, alpha, and beta bands. The results showed that the theta power at the frontal midline decreased with increased arousal level related to tempo. The alpha power induced by original music at the bilateral occipital-parietal regions was stronger than that by tempo-transformed music. The beta power did not change with tempo. At the network level, the original music-related alpha network had high global efficiency and the optimal path length. This study was the first to use EEG to investigate multi-oscillatory activities and the data support the tempo-specific timing hypothesis.
在目前的研究中,我们使用脑电图(EEG)来研究音乐节奏感知与特定脑区的振荡活动之间的关系,以及 theta、alpha 和 beta 波段的头皮 EEG 网络。结果表明,与节奏相关的唤醒水平增加时,额中线的 theta 功率降低。原始音乐在双侧枕顶区域引起的 alpha 功率强于节奏转换音乐。beta 功率不随节奏而变化。在网络层面上,与原始音乐相关的 alpha 网络具有较高的全局效率和最佳路径长度。这项研究首次使用 EEG 研究多振荡活动,数据支持节奏特异性计时假说。
