在执行自定进度的双手和单手敲击任务期间，使用功能磁共振成像测量了两名专业钢琴演奏者和两名仔细匹配的非音乐家对照受试者的血流动力学反应。选择双手任务是因为它们类似于钢琴家在钢琴练习中必须产生的典型动作。结果表明，专业钢琴家的主要和次要运动区（M1、SMA、前 SMA 和 CMA）被激活，但程度比非音乐家要低得多。这种差异在 SMA 和 CMA 之前最为明显，专业钢琴家在这两个时期表现出的激活程度非常低。结果表明，钢琴家长期广泛的手部技能训练可以提高效率，这反映在执行给定手指动作所需的活跃神经元数量较少。这反过来又扩大了对各种运动的可能控制能力，因为更多的运动或更多的“自由度”是可以控制的。 (C) 2000 Elsevier Science B.V. 保留所有权利。
Hemodynamic responses were measured applying functional magnetic resonance imaging in two professional piano players and two carefully matched non-musician control subjects during the performance of self-paced bimanual and unimanual tapping tasks. The bimanual tasks were chosen because they resemble typical movements pianists have to generate during piano exercises. The results showed that the primary and secondary motor areas (M1, SMA, pre-SMA, and CMA) were considerably activated to a much lesser degree in professional pianists than in non-musicians. This difference was strongest for the pre-SMA and CMA, where professional pianists showed very little activation. The results suggest that the long lasting extensive hand skill training of the pianists leads to greater efficiency which is reflected in a smaller number of active neurons needed to perform given finger movements. This in turn enlarges the possible control capacity for a wide range of movements because more movements, or more 'degrees of freedom', are controllable. (C) 2000 Elsevier Science B.V.
