神经成像研究表明，熟练音乐家的大脑对音乐刺激的反应与非音乐家的大脑不同，特别是对于那些从小就开始练习的音乐家。与音乐技能相关的大脑属性是归因于音乐练习还是影响音乐训练决定的遗传特征是一个有争议的话题，因为它具有教育学意义。在这里，我们报告说，听觉皮层的代表性测量神经磁性的音调不同的音色（小提琴和小号）相比，小提琴手和小号手的正弦音调，优先为音色的培训。音色特异性是由使用依赖可塑性的原则预测的，并对与音乐技能相关的大脑属性的先天性解释提出了新的要求。NeuroReport 12：169-174（C）2001 Lippincott威廉姆斯和威尔金斯。
Neural imaging studies have shown that the brains of skilled musicians respond differently to musical stimuli than do the brains of non-musicians, particularly for musicians who commenced practice at an early age. Whether brain attributes related to musical skill are attributable to musical practice or are hereditary traits that influence the decision to train musically is a subject of controversy, owing to its pedagogic implications. Here we report that auditory cortical representations measured neuromagnetically for tones of different timbre (violin and trumpet) are enhanced compared to sine tones in violinists and trumpeters, preferentially for timbres of the instrument of training. Timbre specificity is predicted by a principle of use-dependent plasticity and imposes new requirements on nativistic accounts of brain attributes associated with musical skill.
