Group-level test-retest reliability assessment using systemic physiology augmented functional near-infrared spectroscopy during a passive-listening task.

ABSTRACT:

Significance

Functional near-infrared spectroscopy (fNIRS) is a valuable neuroimaging technique for auditory-research tasks. However, fNIRS data are influenced by systemic-physiological processes, resulting in noisier signal quality that may compromise test-retest reliability. fNIRS reliability may also be influenced by changes in cap placement across sessions.

Aim

We investigated the effectiveness of systemic-physiology denoising methods on the test-retest reliability of group-level fNIRS data during a passive-listening task.

Approach

Fifteen participants completed two identical sessions of a passive-listening task; source-detector optode locations were digitized for each session. Different denoising methods were compared to investigate the effect of systemic-physiol
