The neuronal processes underlying dance observation have been the focus of an increasing number of brain imaging studies over the past decade. However, the existing literature mainly dealt with effects of motor and visual expertise, whereas the neural and cognitive mechanisms that underlie the interpretation of dance choreographies remained unexplored. Hence, much attention has been given to the action observation network (AON) whereas the role of other potentially relevant neuro-cognitive mechanisms such as mentalizing (theory of mind) or language (narrative comprehension) in dance understanding is yet to be elucidated. We report the results of an fMRI study where the structural coherence of short contemporary dance choreographies was manipulated parametrically using the same taped movement material. Our participants were all trained dancers. The whole-brain analysis argues that the interpretation of structurally coherent dance phrases involves a subpart (superior parietal) of the AON as well as mentalizing regions in the dorsomedial prefrontal cortex. An ROI analysis based on a similar study using linguistic materials (Pallier et al., 2011) suggests that structural processing in language and dance might share certain neural mechanisms.
在过去十年中，舞蹈观察背后的神经过程一直是越来越多脑成像研究的重点。然而，现有文献主要关注运动和视觉专业技能的影响，而舞蹈编排解读背后的神经和认知机制仍未得到探索。因此，人们对动作观察网络（AON）给予了很多关注，而其他潜在相关的神经认知机制，如心理化（心理理论）或语言（叙事理解）在舞蹈理解中的作用尚待阐明。我们报告了一项功能磁共振成像（fMRI）研究的结果，该研究使用相同的录像动作材料对当代短舞蹈编排的结构连贯性进行了参数化操作。我们的参与者都是受过训练的舞者。全脑分析表明，对结构连贯的舞蹈乐句的解读涉及动作观察网络的一个子部分（顶上叶）以及背内侧前额叶皮层中的心理化区域。基于一项使用语言材料的类似研究（Pallier等人，2011年）的感兴趣区域（ROI）分析表明，语言和舞蹈中的结构处理可能共享某些神经机制。
