High-Density Multi-Distance fNIRS Enhances Detection of Brain Activity during a Word-Color Stroop Task.

ABSTRACT:

Significance

Functional Near-Infrared Spectroscopy (fNIRS) enables neuroimaging in scenarios where other modalities are less suitable, such as during motion tasks or in low-resource environments. Sparse fNIRS arrays with 30mm channel spacing are widely used but have limited spatial resolution. High-density (HD) arrays with overlapping, multi-distance channels improve sensitivity and localization but increase costs and setup times. A statistical comparison of HD and sparse arrays is needed for evaluating the benefits and trade-offs of HD arrays.

Aim

This study provides a statistical comparison of HD and sparse fNIRS performance to inform array selection in future research.

Approach

We measured prefrontal cortex (PFC) activation during congruent and incongruent Word-Col
