Fig. 2: Experimental procedure for the fNIRS recording at birth.
From: Prenatal linguistic exposure shapes language brain responses at birth
A A newborn participant with the fNIRS headgear in their crib. B Probe placement and their approximate spatial projection onto a newborn MRI brain template. Coupling of light sources (red dots) and detectors (black dots) yielded a total of 72 channels (colored lines). Colors represent the six regions of interest (ROI) subdivisions identified in the left (LH) and right (RH) hemispheres based on anatomical landmarks and 10-10 coordinates82. C Example of the experimental paradigm. The three languages were presented in blocks of three consecutive story segments of the same language (French (FR) in black, German (GE) in red, and Hebrew (HE) in blue). The order of the languages was randomized and counterbalanced across participants.
