Fig. 5From: A functional near-infrared spectroscopy study on hemodynamic changes of patients with prolonged disorders of consciousness responding to different auditory stimuliThe hemodynamic changes in pDoC patients during SON and MI tasks. pDoC patients, including MCS and VS patients, received SON and MI tasks as indicated. The concentrations of HbO (A) and HbR (C) were recorded. The fitting slope of HbO and HbR are presented in B and D, respectivelyBack to article page
