Different music training involves different hand coordination levels and may have a significant influence on brain oscillation for the executive function. However, few research has focused on the plasticity of executive function and the brain oscillation modulated by different musical instrument training modules. In this study, we recruited 18 string musicians, 20 pianists, and 19 non-musicians to perform a bimanual key pressing task during EEG recording. Behavioral results revealed that pianists have the highest accuracy and the shortest response time, followed by string musicians and non-musicians (p < 0.05). Time-frequency analyses of EEG revealed that pianists generated significantly greater theta power than the other groups from 500 ms to 800 ms post-stimulus in mid-central, frontal brain areas, and motor control areas. Functional connectivity analyses found that the pianists showed significantly greater connectivity in the frontal-parietal area in theta band based on phase-locking value analysis, which suggests that piano training improves executive function and enhances the connectivity between prefrontal and mid-central regions. These findings contribute to a better understanding of the effects of different music training on executive function.
不同的音乐训练涉及不同的手部协调水平，并且可能对执行功能的脑振荡产生重大影响。然而，很少有研究关注执行功能的可塑性以及由不同乐器训练模块调制的脑振荡。在本研究中，我们招募了18名弦乐器演奏者、20名钢琴演奏者和19名非音乐家，在脑电图（EEG）记录期间执行双手按键任务。行为结果显示，钢琴演奏者的准确性最高，反应时间最短，其次是弦乐器演奏者和非音乐家（p < 0.05）。EEG的时频分析显示，在刺激后500毫秒至800毫秒期间，钢琴演奏者在中中央、额叶脑区和运动控制区产生的θ波功率明显大于其他组。功能连接性分析发现，基于锁相值分析，钢琴演奏者在θ波段的额顶叶区域显示出明显更强的连接性，这表明钢琴训练改善了执行功能，并增强了前额叶和中中央区域之间的连接性。这些发现有助于更好地理解不同音乐训练对执行功能的影响。
