Anecdotal and some empirical evidence suggests that music can enhance learning and memory. However, the mechanisms by which music modulates the neural activity associated with learning and memory remain largely unexplored. We evaluated coherent frontal oscillations in the electroencephalogram (EEG) while subjects were engaged in a modified version of Rey's Auditory Verbal Learning Test (AVLT). Subjects heard either a spoken version of the AVLT or the conventional AVLT word list sung. Learning-related changes in coherence (LRCC) were measured by comparing the EEG during word encoding on correctly recalled trials to the immediately preceding trial on which the same word was not recalled. There were no significant changes in coherence associated with conventional verbal learning. However, musical verbal learning was associated with increased coherence within and between left and right frontal areas in theta, alpha, and gamma frequency bands. It is unlikely that the different patterns of LRCC reflect general performance differences; the groups exhibited similar learning performance. The results suggest that verbal learning with a musical template strengthens coherent oscillations in frontal cortical networks involved in verbal encoding.
轶事和一些实证证据表明，音乐可以增强学习和记忆。然而，音乐调节与学习和记忆相关的神经活动的机制在很大程度上仍未得到探索。我们在受试者进行改良版的雷伊听觉词语学习测验（AVLT）时，评估了脑电图（EEG）中的额叶相干振荡。受试者听取AVLT的口语版本或演唱的传统AVLT单词列表。通过将正确回忆试验中单词编码期间的脑电图与前一次未回忆起同一单词的试验的脑电图进行比较，测量与学习相关的相干性变化（LRCC）。传统言语学习中相干性没有显著变化。然而，音乐言语学习与左右额叶区域内以及之间在θ、α和γ频段的相干性增加有关。LRCC的不同模式不太可能反映一般的表现差异；两组表现出相似的学习表现。结果表明，使用音乐模板进行言语学习可增强参与言语编码的额叶皮质网络中的相干振荡。
