自然环境中的神经监测越来越引起包括心理学、经济学和生产力在内的各种研究领域的兴趣。在功能性神经监测模式中，功能性近红外光谱 (fNIRS) 因其小型化潜力、良好的空间和时间分辨率以及对运动伪影的恢复能力而备受推崇。从历史上看，fNIRS 系统的大尺寸和高成本阻碍了该技术的广泛采用。在本文中，我们描述了第一个开源、完全集成的无线 fNIRS 头带系统，具有单个 LED 对光源和四个探测器。考虑到操作简便性和舒适性，该系统采用柔软、轻质的布料和硅胶外壳包裹。还提供了随附的计算机和智能手机数据收集软件，并且硬件已使用经典的 fNIRS 任务进行了验证。这种即戴式设计可以轻松扩展，以适应更多数量的 fNIRS 通道，并为在自然条件下的日常活动中轻松收集 fNIRS 数据打开了大门。
Neuromonitoring in naturalistic environments is of increasing interest for a variety of research fields including psychology, economics, and productivity. Among functional neuromonitoring modalities, functional near-infrared spectroscopy (fNIRS) is well regarded for its potential for miniaturization, good spatial and temporal resolutions, and resilience to motion artifacts. Historically, the large size and high cost of fNIRS systems have precluded widespread adoption of the technology. In this article, we describe the first open source, fully integrated wireless fNIRS headband system with a single LED-pair source and four detectors. With ease of operation and comfort in mind, the system is encased in a soft, lightweight cloth and silicone enclosure. Accompanying computer and smartphone data collection software have also been provided, and the hardware has been validated using classic fNIRS tasks. This wear-and-go design can easily be scaled to accommodate a larger number of fNIRS channels and opens the door to easily collecting fNIRS data during routine activities in naturalistic conditions.
