The Society for functional near-infrared spectroscopy (SfNIRS) is a professional organization of basic and clinical scientists who seek to understand the functional properties of biological tissues, especially the brain, using optical methods. The aim of the Society is to promote the exchange of ideas, interdisciplinary collaboration, and education.

The purpose of this website is to help strengthen the community by providing information about instruments, probes, analysis software, related meetings, publications, and more.

fNIRS 2020

The next conference will be held in Boston, MA, October 11-14, 2020. Save the date!


The Society for fNIRS has adopted Neurophotonics as its official journal. Please consider submitting your next relevant article there.

Founded in 2014, Neurophotonics has had a healthy start in indexing, submissions, and citations:

  • PubMed, PubMed Central, Scopus, Ei Compendex, Web of Science-SCIE, and Inspec include the journal in their indexes. It is covered by all the major relevant search services.
  • In 2017, 78 articles were published.
  • In the current citation indexing year, Neurophotonics received the following scores:
    • Two-year impact factor: 4.129
    • Five-year impact factor: 4.319
    • CiteScore, a three-year Scopus metric: 3.52
  • Neurophotonics has the following placement in its CiteScore categories:
    • 92nd percentile for the CiteScore Medicine-Radiology, Nuclear Medicine and Imaging
    • 90th percentile for Health Professions-Radiological and Ultrasound Technology
    • 82nd percentile for Neuroscience (miscellaneous).

In July 2018, Neurophotonics adopted a gold open access publishing model; the APC must be paid for articles to be published in the 2019 volume. Affiliates of SPIE Digital Library subscribing institutions and SPIE members will receive a 25% discount from the standard $1,675 APC.

Members of SfNIRS can obtain a membership rate for subscribing to the journal through SPIE using the SfNIRS member-only form provided here.
