Webmacro-anatomical regions are difficult to consistently define, others are more stable and fNIRS channels on an age-appropriate MRI template are often consistent with individual infant MRIs. We have generated a standard-ized scalp surface map of fNIRS channel locators to reliably locate cortical regions for fNIRS developmental researchers. WebNIRS Lab Equipment Our lab provides the tools and space for researchers to carry out their fNIRS projects. Visit our wiki to get more detailed information on our equipment and operations..
