Cui, Bryant, Reiss (2012) NIRS-based hyperscanning reveals increased interpersonal coherence in superior frontal cortex during cooperation NeuroImage 59(3) 2430-7

Abstract

We used Near-Infrared Spectroscopy (NIRS) to simultaneously measure brain activity in two people while they played a computer-based cooperation game side by side. Inter-brain activity coherence was calculated between the two participants. We found that the coherence between signals generated by participants' right superior frontal cortices increased during cooperation, but not during competition. Increased coherence was also associated with better cooperation performance. To our knowledge, this work represents the first use of a single NIRS instrument for simultaneous measurements of brain activity in two people. This study demonstrates the use of NIRS-based hyperscanning in studies of social interaction in a naturalistic environment. Copyright © 2011 Elsevier Inc. All rights reserved.

我们使用近红外光谱(NIRS)同时测量两个人的大脑活动,而他们玩一个基于计算机的合作游戏并排。计算两个参与者之间的脑内活动相干性。我们发现,参与者的右前额皮质产生的信号之间的一致性在合作期间增加,但在竞争期间不增加。增加的一致性也与更好的合作绩效有关。据我们所知,这项工作代表单个NIRS仪器的第一次使用同时测量两个人的大脑活动。这项研究表明基于NIRS的overerscan在自然主义环境中的社会交互的研究中的使用。
