A Functional Near-infrared Spectroscopy Study to Detect Activation of Somatosensory Cortex by Peripheral Nerve Stimulation

摘要

Multi-channel near-infrared spectroscopy (NIRS) is a method for non-invasively monitoring of relative concentrations of oxygenated, deoxygenated, and total hemoglobin. This technique has found expanding application in brain mapping and functional imaging. The purpose of this study was to investigate whether activation of somatosensory cortex can be detected without the necessity of the patient’s cooperation in performing a task.
