演奏音乐需要快速的听觉和运动处理。关于专业音乐家，最近的脑成像研究表明，听觉刺激会产生运动区的共同激活，而音乐短语的无声敲击会引起听觉区域的共同激活。这是否是通过特定的大脑中继站获得的尚不清楚。此外，可塑性的时间过程尚未得到解决。本研究观察了短时间（20分钟）和长时间（5周）钢琴学习在听觉和运动任务中引起的皮层激活模式（DC-EEG电位）的变化。两个初学者组进行了培训。“映射”组被允许学习标准的钢琴键到音高映射。对于“无映射”组，随机分配按键到音调阻止了这样的映射。听觉-感觉运动EEG共活动仅在20分钟内发生。经过5周的训练后，效果得到了增强，感知和行动的元素都有助于仪器的心理表征。“地图”组表现出显着的额外活动的右前区。我们的结论是，音乐训练触发大脑皮层的即时可塑性，右半球前部区域提供了一个听觉-运动界面的心理表征的键盘。
Performing music requires fast auditory and motor processing. Regarding professional musicians, recent brain imaging studies have demonstrated that auditory stimulation produces a co-activation of motor areas, whereas silent tapping of musical phrases evokes a co-activation in auditory regions. Whether this is obtained via a specific cerebral relay station is unclear. Furthermore, the time course of plasticity has not yet been addressed. Changes in cortical activation patterns (DC-EEG potentials) induced by short (20 minute) and long term (5 week) piano learning were investigated during auditory and motoric tasks. Two beginner groups were trained. The 'map' group was allowed to learn the standard piano key-to-pitch map. For the 'no-map' group, random assignment of keys to tones prevented such a map. Auditory-sensorimotor EEG co-activity occurred within only 20 minutes. The effect was enhanced after 5-week training, contributing elements of both perception and action to the mental representation of the instrument. The 'map' group demonstrated significant additional activity of right anterior regions. We conclude that musical training triggers instant plasticity in the cortex, and that right-hemispheric anterior areas provide an audio-motor interface for the mental representation of the keyboard.
