Abstract:

Motor coordination plays a crucial role in the establishment of social interactions. Previous studies have focused on single-limb coordination, neglecting two-limb coordination. The current study adopted a novel experimental paradigm, a bilateral stepping task of different modes (in-phase/anti-phase) when two participants performed the stepping coordination. In addition to behavioral performance, the brain activity of both interacting parties was simultaneously recorded by using the fNIRS hyperscanning. The results revealed stronger neural activity in certain regions of interest (corresponding to the bilateral inferior parietal lobule) during intra-individual coordination as compared to inter-individual coordination for both in-phase and anti-phase patterns. Therefore, the inferior parietal lobule may be potentially the critical neural basis for motor coordination.

Key words: motor coordination, fNIRS, hyperscanning

摘要:

动作同步在人际关系的建立过程中起着重要作用。以往的动作同步研究大多涉及单个肢体/物体,本研究设置需要双侧肢体协调的踏步任务,使用近红外超扫描技术同步采集互动双方的大脑活动,探究单人协调与动作同步(同相和反相)的大脑激活方式以及行为方面的差异。结果发现,在双侧下顶叶单人协调的神经激活显著高于同相模式和反相模式,表明下顶叶可能是动作同步的重要神经基础。
