Figure 2. fNIRS and eye-tracking setup.

Figure 2

Dual-brain hyperscanning setup using the Shimadzu LABNIRS is shown for two illustrative participants. The optode layout consists of 16 detector and emitter pairs per cap configured to provide 42 channels per participant. fNIRS signals were synchronized across participants and the eye-tracking system. A. Participant 1 views the right eye (orange circle, upper panel) and left eye (orange circle, lower panel) of participant 2. B. Participant 2 views the right eye (yellow circle, upper panel) and left eye (yellow circle, lower panel) of Participant 1. These calibrations demonstrate position accuracy related to gaze position.
