Abstract

This experiment proposes a multi-modal measurement using near-infrared spectroscopy (NIRS) and electroencephalography (EEG) using a novel NIRS/EEG device to measure the effect of subjective pain on Gamma-band (GBO) and hemodynamic changes. A customized NIRS/EEG probe was designed and implemented. The NIRS/EEG signals were recorded during the cold pressor test (CPT). The experiment began with two minutes baseline, followed by two minutes CPT and repeated three times for each subject. The GBO extracted from the EEG signal was detected during subjective pain (CPT). The increase of tissue total blood volume associated with the rise of GBO power was observed and reported.
