Hyperscanning functional magnetic resonance imaging (fMRI) was developed to gain deeper insight into the neural basis of social cognition. Simultaneous imaging of brain activity in multiple subjects facilitates analysis of the neural basis of real-time interactions and communication. This method reveals the neural basis of social interactions, including inter-individual synchronization as a phenomenon that cannot be reduced to individuals. This modality enables research into the neural mechanisms underlying social interactions that are integral to many aspects of our lives. I will outline the background, current status, and prospects of development of hyperscanning fMRI, which may be an important methodology in the shift from "first-person" neuroscience (which refers to the interaction between individuals and the environment) to "second-person" neuroscience (which refers to the application of neuroscientific methods to investigate inter-individual associations).
超扫描功能磁共振成像（fMRI）的开发是为了更深入地了解社会认知的神经基础。对多个受试者的大脑活动进行同步成像，有助于分析实时互动和交流的神经基础。这种方法揭示了社会互动的神经基础，包括个体间同步，这是一种不能简化为个体的现象。这种模式能够研究社会互动背后的神经机制，而社会互动是我们生活中许多方面不可或缺的一部分。我将概述超扫描fMRI的背景、现状和发展前景，它可能是从“第一人称”神经科学（指个体与环境之间的互动）向“第二人称”神经科学（指应用神经科学方法研究个体间关联）转变过程中的一种重要方法。
