Abstract

Near-infrared spectroscopy (NIRS) based optical imaging systems have been widely used in functional brain studies as a noninvasive tool to monitor changes in the concentration of oxygenated hemoglobin (oxy-Hb) and deoxygenated hemoglobin (deoxy-Hb). Based on the NIRS technique, Drexel University’s Optical Brain Imaging group has developed a functional brain monitoring system (fNIR) to assess cognitive and motor activities of healthy subjects and patients. The fNIR is a portable, safe, affordable and negligibly intrusive monitoring system which enables the study of cortical activation-related hemodynamic changes in various field conditions. This presentation focuses on applications of the fNIR in a variety of natural and clinical settings including human performance studies, neurorehabilitation, anesthesiology, pediatric monitoring as well as training and education. The experimental set-up, procedures and data analysis of the fNIR measurements acquired from the forehead during aforementioned studies will be presented.
