Abstract :
We propose to embed a continuous-wave near-infrared spectroscopy system within an electroencephalography system to perform functional hemodynamic and neural response simultaneously. In this study, we present the measuring system and the results consisting in changes of oxyhemoglobin and deoxyhemoglobin derived from continuous-wave near-infrared spectroscopy data and the evoked potential responses derived from the electroencephalography recordings. A checkerboard stimulus was adopted to elicit a response signal from the visual cortex. The results collected demonstrate that near infrared spectroscopy can detect task-induced changes in homodynamic
