Abstract

Neuroimaging studies struggle from inter- and intra-subject variability of collected data. To overcome these barriers to statistical significance, researchers are pursuing naturalistic neuroimaging to increase the statistical power of their investigations. Although numerous devices have become available for prefrontal cortex imaging, fNIRS systems continue to struggle with significant weight (>200g) and dependence on experts for setup. Our group has developed an ergonomic fNIRS headset and an accompanying Android augmented reality (AR) app for system setup by lay users. The combination of low-cost technology with user-friendly guidance for accurate setup will enable new studies in naturalistic conditions.
