devfOLD: a toolbox for designing age-specific fNIRS channel placement
Xiaoxue Fu, John E. Richards
Abstract
Significance: Near-infrared spectroscopy (NIRS) is a noninvasive technique that uses scalpplaced sensors to measure cerebral hemoglobin concentration. Commercial NIRS instruments do not allow for whole-head coverage and do not intrinsically indicate which brain areas generate the NIRS signal. Hence, the challenge is to design source-detector channel arrangement that maximizes sensitivity to a given brain region of interest (ROI). Existing methods for optimizing channel placement design have been developed using adult head models. Thus, they have limited utility for developmental research.
