音乐家在躯体感觉和听觉领域表现出非凡的运动模式和感觉处理能力。这些过程中有许多是特定于所用仪器的。我们感兴趣的是大脑和小脑的代表性，这些仪器的具体变化，因此应用功能性磁共振成像（fMRI）在两组乐器演奏家不同的工具培训可比的时期（约15年）。第一组（小号演奏者）使用手指和嘴唇的紧密互动;第二组（钢琴家作为对照组）只使用四肢进行表演。功能磁共振成像任务是平衡的指示（钢琴和小号音符），感觉反馈（键盘和小号），手唇互动的小号。在功能磁共振成像中，两组人在不同的设备（喇叭或键盘）之间切换，并结合或不结合听觉反馈的性能。在没有任何音调发射的情况下演奏小号或使用吹口显示出小号演奏者的乐器训练特定激活增加。这在小脑后上半球、主要的初级感觉运动皮层和左侧Heschl回中是明显的。此外，小号演奏者在实际小号演奏过程中显示出双侧Heschl's gyrus的活动增加，尽管与钢琴家相比，他们在扫描仪中使用吹口时显示出显著降低的响度。(C)2013 Elsevier Inc.

Musicians show a remarkable ability to interconnect motor patterns and sensory processing in the somatosensory and auditory domains. Many of these processes are specific for the instrument used. We were interested in the cerebral and cerebellar representations of these instrument-specific changes and therefore applied functional magnetic resonance imaging (fMRI) in two groups of instrumentalists with different instrumental training for comparable periods (approximately 15 years). The first group (trumpet players) uses tight finger and lip interaction; the second (pianists as control group) uses only the extremities for performance. fMRI tasks were balanced for instructions (piano and trumpet notes), sensory feedback (keypad and trumpet), and hand-lip interaction on the trumpet. During fMRI, both groups switched between different devices (trumpet or keypad) and performance was combined with or without auditory feedback. Playing the trumpet without any tone emission or using the mouthpiece showed an instrument training-specific activation increase in trumpet players. This was evident for the posterior-superior cerebellar hemisphere, the dominant primary sensorimotor cortex, and the left Heschl's gyrus. Additionally, trumpet players showed increased activity in the bilateral Heschl's gyrus during actual trumpet playing, although they showed significantly decreased loudness while playing with the mouthpiece in the scanner compared to pianists.
