A reference-channel based methodology to improve estimation of event-related hemodynamic response from fNIRS measurements

► Estimation of stimulus-evoked hemodynamic activity in the human cortex using fNIRS ► A novel approach to increase signal-to-noise ratio of the hemodynamic response ► Sizable accuracy improvements demonstrated using both artificial and human data ► No need for a-priori information on hemodynamic response's profile ► Applicable to a large class of fNIRS experiments, including event-related designs
