The fNIRS Glossary Project: A Community-Sourced Glossary of Key Terms
April 28th 2025Established to develop a community-sourced glossary covering key functional near-infrared spectroscopy (fNIRS) terms, including those related to the continuous-wave (CW), frequency-domain (FD), and time-domain (TD) NIRS techniques, the fNIRS Glossary Project features over 300 terms categorized into six key domains: analysis, experimental design, hardware, neuroscience, mathematics, and physics. It also includes abbreviations, symbols, synonyms, references, alternative definitions, and figures where relevant.
