There is growing interest in developing training programs to mitigate cognitive decline associated with normal aging. Here, we assessed the effect of 3-month music and visual art training programs on the oscillatory brain activity of older adults using a partially randomized intervention design. High-density electroencephalography (EEG) was measured during the pre- and post-training sessions while participants completed a visual GoNoGo task. Time-frequency representations were calculated in regions of interest encompassing the visual, parietal, and prefrontal cortices. Before training, NoGo trials generated greater theta power than Go trials from 300 to 500 ms post-stimulus in mid-central and frontal brain areas. Theta power indexing response suppression was significantly reduced after music training. There was no significant difference between pre- and post-test for the visual art or the control group. The effect of music training on theta power indexing response suppression was associated with reduced functional connectivity between prefrontal, visual, and auditory regions. These results suggest that theta power indexes executive control mechanisms in older adults. Music training affects theta power and functional connectivity associated with response suppression. These findings contribute to a better understanding of inhibitory control ability in older adults and the neuroplastic effects of music interventions.

音乐训练调节与反应抑制相关的 θ 脑振荡

人们越来越有兴趣开发培训计划来减轻与正常衰老相关的认知能力下降。在这里,我们使用部分随机干预设计评估了为期 3 个月的音乐和视觉艺术训练计划对老年人大脑振荡活动的影响。在参与者完成视觉 GoNoGo 任务的同时,在训练前后测量高密度脑电图 (EEG)。在包括视觉、顶叶和前额皮质的感兴趣区域中计算时频表示。训练前,在刺激后 300 至 500 毫秒内,NoGo 试验在中枢和额叶大脑区域产生了比 Go 试验更大的 theta 功率。音乐训练后,Theta 功率指数反应抑制显着降低。视觉艺术或对照组的测试前后没有显着差异。音乐训练对 theta 功率指数反应抑制的影响与前额叶、视觉和听觉区域之间的功能连接减少有关。这些结果表明,theta 功率索引了老年人的执行控制机制。音乐训练会影响与反应抑制相关的 θ 功率和功能连接。这些发现有助于更好地了解老年人的抑制控制能力和音乐干预的神经塑性效应。
