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.
Vision
A global home for functional near-infrared spectroscopy (fNIRS) serving both the scientific community and the public, fostering fNIRS as a high-performance, naturalistic, neuroimaging modality that drives transformative scientific research with high societal impact.
Mission
We promote fNIRS by uniting developers and users and disseminating fNIRS capabilities and value to the broader scientific community and the public. To advance and share knowledge, we engage researchers across industry, government, and academia. To enhance performance, we develop standards for data structures, sharing, processing, and instrumentation. To deepen societal impact, we foster neuroimaging paradigms that address biomedical and biological questions. To sustain progress in the field, we train the next generation of fNIRS scientists.
