Abstract

Purpose

Some studies have explored the relationship between music and cortical activities; however, there are just few studies investigating guitar performance associated with different sensory stimuli. Our aim was to evaluate alpha and beta activity during guitar playing.

Materials and Method

Twenty healthy right-handed people participated in this study. Cortical activity was measured by electroencephalogram (EEG) during rest and 4 tasks (1: easy music with an auditory stimulus; 2: easy music with an audiovisual stimulus; 3: complex music with an auditory stimulus; 4: complex music with an audiovisual stimulus). The peak frequency (PF), median frequency (MF) and root mean square (RMS) of alpha and beta EEG signals were assessed.

Results

A higher alpha PF at the T3-P3 was observed, and this difference was higher between rest and task 3, rest and task 4, tasks 1 and 3, and tasks 1 and 4. For beta waves, a higher PF was observed at C4-P4 and a higher RMS at C3-C4 and O1-O2. At C4-P4, differences between rest and tasks 2 and 4 were observed. The RMS of beta waves at C3-C4 presented differences between rest and task 3 and at O1-O2 between rest and task 2 and 4.

Conclusion

The action observation of audiovisual stimuli while playing guitar can increase beta wave activity in the somatosensory and motor cortexes; and increase in the alpha activity in the somatosensory and auditory cortexes and increase in the beta activity in the bilateral visual cortexes during complex music execution, regardless of the stimulus type received.

吉他演奏期间的 Alpha 和 Beta 皮质活动：任务复杂性和视听刺激分析。

摘要

目的

一些研究探讨了音乐与皮层活动之间的关系；然而，很少有研究调查与不同感官刺激相关的吉他演奏。我们的目标是评估吉他演奏期间的 alpha 和 beta 活动。

材料和方法

20 名健康的右利手参加了这项研究。在休息和 4 个任务（1：带有听觉刺激的简单音乐；2：带有视听刺激的简单音乐；3：带有听觉刺激的复杂音乐；4：带有视听刺激的复杂音乐）期间，通过脑电图 (EEG) 测量皮质活动）。评估了 alpha 和 beta EEG 信号的峰值频率 (PF)、中值频率 (MF) 和均方根 (RMS)。

结果

在 T3-P3 观察到更高的 α PF，在休息和任务 3、休息和任务 4、任务 1 和 3、任务 1 和 4 之间的差异更大。对于 β 波，在 C4 观察到更高的 PF -P4 和更高的 RMS 在 C3-C4 和 O1-O2。在 C4-P4，观察到休息与任务 2 和 4 之间的差异。C3-C4 β 波的 RMS 在休息和任务 3 之间以及 O1-O2 处在休息和任务 2 和 4 之间呈现差异。

结论

弹奏吉他时对视听刺激的动作观察可以增加体感和运动皮层的β波活动；在复杂的音乐执行过程中，无论接受何种刺激类型，体感和听觉皮层中 α 活动的增加以及双侧视觉皮层中 β 活动的增加。
