Phase component of frequency-domain functional near-infrared imaging improves decoding of motor-evoked neural activity

Frequency-domain functional near-infrared spectroscopy (FD-fNIRS) has the potential to improve neural imaging of brain hemodynamic responses over conventional magnitude measurements from continuous wave (CW) fNIRS systems by providing additional measurement of phase changes. We evaluated whether phase measurements improved accuracy in decoding motor activity and laterality of movement while record...
