To analyze brain connectivity dynamics during listening to music and estimate the potential impact on task performance. Fifteen participants (13 males and 2 females) participated in this study based on their interest in Indian classical music. Measurements of the influence of Indian music on task performance were obtained by assessing brain activation using EEG signals. Brain connectivity analysis was performed to visualize the connections between brain regions under various experimental conditions. Visual Go/No Go Stimuli was used to evaluate visual spatial attention during operation by evaluating misses, committed errors, and reaction times. In Task 1 (listening to music only), it was reported that there was a change in the positions of the electrodes (F3, F7) located in the left frontal lobe. The energy of the relative beta component was significantly higher only at F7 during task 1 ( = 0.005). Event-related desynchronization alpha and theta synchronization were significant ( = 0.005) at all electrode sites in the bilateral frontal lobes (F3, F4, F7 and F8) while listening to music and performing tasks (task 2). When the task without music (task 3) was performed, the energy of the relative alpha component was significantly higher at the Fp2 electrode position ( = 0.005). It is noteworthy that the energy of the theta component was significantly lower at the location of the Fp2 electrode ( = 0.005). The frontal asymmetry index score measures were significantly high at F4/F3 and F8/F7 during task 1. The connectivity map of theta synchronization showed a robust association between Fp2 and F8 which was in turn connected to P4 and O2 during Task 2. Results indicated an increased omission and commission errors during Task 3.
分析听音乐时的大脑连接动态，并估计其对任务表现的潜在影响。15名参与者（13名男性和2名女性）基于对印度古典音乐的兴趣参与了本研究。通过使用脑电图信号评估大脑激活来获得印度音乐对任务表现影响的测量结果。进行大脑连接分析以可视化各种实验条件下大脑区域之间的连接。视觉Go/No Go刺激用于通过评估漏报、犯错误和反应时间来评估操作过程中的视觉空间注意力。在任务1（仅听音乐）中，据报道位于左额叶的电极（F3、F7）位置发生了变化。在任务1期间，仅F7处的相对β成分能量显著更高（=0.005）。在听音乐并执行任务（任务2）时，双侧额叶（F3、F4、F7和F8）所有电极部位的事件相关去同步化α和θ同步化均显著（=0.005）。当执行无音乐任务（任务3）时，Fp2电极位置的相对α成分能量显著更高（=0.005）。值得注意的是，Fp2电极位置的θ成分能量显著更低（=0.005）。在任务1期间，F4/F3和F8/F7处的额叶不对称指数得分显著较高。θ同步化的连接图显示，在任务2期间，Fp2和F8之间存在强烈关联，而F8又与P4和O2相连。结果表明，在任务3期间漏报和犯错误增加。
