Fast cerebral functional signal in the 100-ms range detected in the visual cortex by frequency-domain near-infrared spectrophotometry.
Brain activity is associated with physiological changes, which alter the optical properties of the tissue in the near-infrared part of the spectrum. Two major types of optical signals following functional brain activation can be distinguished: a slow signal due to hemodynamic changes and a fast signal, which is directly related to neuronal activity. The fast signal is small and therefore diffic...
متن کاملFunctional frequency-domain near-infrared spectroscopy detects fast neuronal signal in the motor cortex.
Millisecond changes in the optical properties of the human brain during stimulation were detected in five volunteers using noninvasive frequency-domain near-infrared spectroscopy. During a motor stimulation task we found highly significant signals, which were directly related to neuronal activity and exhibited much more localized patterns than the slow hemodynamic signals that are also detected...
متن کاملOptical Imaging of the Motor Cortex in the Brain in Order to Determine the Direction of the Hand Movements Using Functional Near-Infrared Spectroscopy (fNIRS)
Introduction: In recent years, optical imaging has attracted a lot of attention from scholars as a non- aggressive, efficient method for evaluating the activities of the motor cortex in the brain. Functional near-infrared spectroscopy (fNIRS (is a tool showing the hemodynamic changes in a cortical area of the brain according to optical principles. The present study has been de...
