It is long known that trained musicians show enhanced cortical processing of musical material. Recent studies showed, however, that already a few weeks of musical training suffice to induce plastic changes in auditory cortical processing, suggesting that sensorimotor learning involved in piano play has quick impact in auditory function. The present proposal builds on these initial findings and explores a number of open questions to better understand how short-term musical training induces brain plasticity. The experiments will use the musical mismatch negativity as a tool to evaluate cortical plasticity with magneto-encephalography (MEG). We will study the neural generators of the musical mismatch negativity using beamformer analysis of MEG data. We will compare the training impact on these generators in normal subjects and in subjects that present amusia, a congenital difficulty to perceive tonal differences and musical relationships. We will also study the impact of short-term piano training on perception in amusics. Using a newly developed instrumental interface for touch-free music playing we will further investigate the interaction of auditory, tactile and motor contributions to musical training and to the associated cortical plasticity. In a new line of research we will begin to apply these tools to the topic of ensemble play. While most neuroscience research in the past has looked at solo performance situations, ensemble play involves many demands and difficulties that are not present in solo play and that highlight important aspects of music production. Using the musical mismatch negativity protocol in a four-hand piano training with two subjects we will look at training benefits, differential error processing, specificity of the training to the individual material, and aspects of corepresentation of motor programs between the two players.

众所周知，受过训练的音乐家对音乐材料的皮层处理能力增强。然而，最近的研究表明，几周的音乐训练已经足以诱导听觉皮层处理的可塑性变化，这表明钢琴演奏中涉及的感觉运动学习对听觉功能有快速影响。目前的建议建立在这些初步发现的基础上，并探讨了一些悬而未决的问题，以更好地了解短期音乐训练如何诱导大脑可塑性。本实验将利用音乐失匹配负波作为脑磁图（MEG）评价大脑皮层可塑性的工具。我们将使用MEG数据的波束形成器分析来研究音乐失配负波的神经发生器。我们将比较训练对正常受试者和失乐症受试者的影响，失乐症是一种先天性的难以感知音调差异和音乐关系的疾病。我们也将研究短期钢琴训练对音乐知觉的影响。使用一个新开发的仪器接口，无触摸音乐播放，我们将进一步研究听觉，触觉和运动的音乐训练和相关的皮层可塑性的贡献的相互作用。在一个新的研究路线中，我们将开始将这些工具应用于合奏的主题。虽然过去大多数神经科学研究都着眼于独奏表演的情况，但合奏涉及独奏演奏中不存在的许多要求和困难，这些要求和困难突出了音乐制作的重要方面。使用音乐失配负协议在四手钢琴训练与两个科目，我们将看看培训的好处，差分错误处理，具体的培训个别材料，和两个球员之间的运动程序的共同表征方面。
