项目摘要

The mirror-neuron system is assumed to be the neural basis for a direct matching between observation and motor representations of actions and is considered to mediate the understanding of actions and intentions. There seems to be a similar system for the auditory domain that matches a heard action to the according motor representation. However, the crossmodal interactions within the system have not yet been systematically investigated: Do the auditory and the visual mirror system share the same neural substrate? If humans learn one action by observation, does the mirror system respond to the sound of the same action? The proposed research project aims at investigating these questions by combining functional magnetic resonance imaging (fMRI) in humans and innovative repetition suppression (RS) paradigms that support a high spatial resolution for the localization of identified brain activity. The actions to be studied will be sequences of finger movements on a piano keyboard, which will be learned in a motor training either by listening to a melody or by observation of finger movements. Furthermore, functional as well as behavioural data will be related to structural data: Differences in white matter pathways in each single participant will be examined using diffusion weighted imaging (DWI), in order to correlate the obtained values to differential performance parameters during a motor training and individual hemodynamic responses in relevant brain areas during a (motor) perception task.

镜像神经元系统被认为是动作的观察和运动表征之间直接匹配的神经基础，并且被认为可以调节对动作和意图的理解。听觉领域似乎有一个类似的系统，将听到的动作与相应的运动表征相匹配。然而，系统内的跨模态相互作用尚未得到系统研究：听觉和视觉镜像系统是否共享相同的神经基质？如果人类通过观察学习一个动作，镜子系统会对同一动作的声音做出反应吗？拟议的研究项目旨在通过结合人类功能磁共振成像（fMRI）和创新的重复抑制（RS）范例来研究这些问题，该范例支持高空间分辨率来定位已识别的大脑活动。要研究的动作将是钢琴键盘上的手指动作序列，这些动作将在运动训练中通过听旋律或观察手指动作来学习。此外，功能和行为数据将与结构数据相关：将使用弥散加权成像（DWI）检查每个参与者白质通路的差异，以便将获得的值与运动训练期间的差异性能参数以及（运动）感知任务期间相关大脑区域的个体血流动力学反应相关联。
