This workshop aims to introduce the NIRX fNIRS Systems to the UHBN users. Functional near-infrared spectroscopy (fNIRS) is a non-invasive neuroimaging technique that measures brain activity by detecting changes in blood oxygenation. The NIRX fNIRS Systems offer advanced capabilities for monitoring and analyzing brain function during various cognitive and behavioral tasks. Participants will learn about the principles of fNIRS, hands-on operation of the NIRX systems, and best practices for data collection and analysis in fNIRS research.
