摘要

学习弹钢琴是一项独特的复杂任务,它融合了多种感官模式和高阶认知功能。对成年新手音乐家进行的纵向神经影像学研究显示,音乐感知任务中与训练相关的功能变化。对实际演奏乐器时大脑活动重组的研究仅局限于一次极短的 fMRI 会话,尚未进行过更长时间的干预。因此,我们的目的是研究在音乐训练的前半年内,弹钢琴时大脑功能重组的动态复杂性。我们使用 fMRI 扫描了 24 名键盘乐器初学者(女性,18-23 岁),他们在经过 1 周、6 周、13 周和 26 周的训练后,弹奏了越来越复杂的音乐作品。弹奏音乐在双侧听觉区、下额叶区、辅助运动区和左侧感觉运动皮层诱发了反应。然而,随着时间的推移,训练效果引起了广泛的变化,包括右侧感觉运动皮层、小脑、顶叶上皮层、岛叶前部和海马等。随着训练的进行,这些区域的激活在播放音乐时有所降低。事后分析表明,独立的听觉和运动相关区域具有特定的时间序列。这些结果表明,虽然主要的感觉、运动和额叶区域与播放音乐有关,但训练减少了高阶认知控制和整合区域以及基底神经节的参与。此外,训练可能会以不同的方式影响不同的大脑区域,这为大脑可塑性的动态性质提供了证据。

Understanding functional brain reorganization for naturalistic piano playing in novice pianists

Understanding functional brain reorganization for naturalistic piano playing in novice pianists

Learning to play the piano is a unique complex task, integrating multiple sensory modalities and higher order cognitive functions. Longitudinal neuroimaging studies on adult novice musicians show training-related functional changes in music perception tasks. The reorganization of brain activity while actually playing an instrument was studied only on a very short time frame of a single fMRI session, and longer interventions have not yet been performed. Thus, our aim was to investigate the dynamic complexity of functional brain reorganization while playing the piano within the first half year of musical training. We scanned 24 novice keyboard learners (female, 18–23 years old) using fMRI while they played increasingly complex musical pieces after 1, 6, 13, and 26 weeks of training. Playing music evoked responses bilaterally in the auditory, inferior frontal, and supplementary motor areas, and the left sensorimotor cortex. The effect of training over time, however, invoked widespread changes encompassing the right sensorimotor cortex, cerebellum, superior parietal cortex, anterior insula and hippocampus, among others. As the training progressed, the activation of these regions decreased while playing music. Post hoc analysis revealed region-specific time-courses for independent auditory and motor regions of interest. These results suggest that while the primary sensory, motor, and frontal regions are associated with playing music, the training decreases the involvement of higher order cognitive control and integrative regions, and basal ganglia. Moreover, training might affect distinct brain regions in different ways, providing evidence in favor of the dynamic nature of brain plasticity.

期刊介绍: The Journal of Neuroscience Research (JNR) publishes novel research results that will advance our understanding of the development, function and pathophysiology of the nervous system, using molecular, cellular, systems, and translational approaches. JNR covers both basic research and clinical aspects of neurology, neuropathology, psychiatry or psychology. The journal focuses on uncovering the intricacies of brain structure and function. Research published in JNR covers all species from invertebrates to humans, and the reports inform the readers about the function and organization of the nervous system, with emphasis on how disease modifies the function and organization.
