多人交互同步记录技术在大脑神经活动测量中的应用*

多人交互同步记录是一种新技术，可以实现同时对多人的脑活动进行测量，现已被越来越多地应用到社会交互的研究中。本文从不同技术角度出发，回顾已经发表的有关多人交互同步记录的研究，从中可以了解不同的脑活动记录技术是如何被应用到各种实验范式中，以及人脑间是如何动态交互的。同时本文也对不同的多人交互同步记录技术的优缺点进行了比较。鉴于该方法的优势，其在未来的社会交互研究中具有广泛的应用前景。

Hyperscanning Used in the Measurement of the Brain Activity

Interpersonal social interaction is considered to be a main characteristic of the social cognition. Measuring brain activity simultaneously among people when interacting is intuitively appealing if the researcher is interested in putative neural markers of social interactions. Hence, the hyperscanning, which can simultaneously record more than one brain in detail, has now been widely used in this field. The devices involved in hyperscanning include electroencephalography ( EEG) , functional magnetic resonance imaging ( fMRI) , and Near-in frared spectroscopy (NIRS) . The studies which have been done with these methods are mainly focus on the following three aspects:Social interaction about the game theory contexts, movement and emotion. As a new approach in this area, there is little review published on this topic. So it is definitely difficult for the newers to have an overall understanding of this technique. This paper reviews many previous but classic studies published, from which we can learn how different recording devices could be applied to experimental paradigms and how the brains interact. As for the great advantages of this technique, it may be more widely used in the research field of social interactions.
