NIRSIT Version 1.0 Operation Manual OBELAB Confidential 5 1 Product features NIRSIT is a brain imaging system utilizing the functional near-infrared spectroscopy and measures the changes in the hemoglobin level in the blood at the prefrontal cortex region. Functional Near Infrared Spectroscopy; fNIRS NIRSIT uses two light waves in the ~700nm and ~800nm range. The device emits light from the lasers pass through the cerebral cortex and measures the changes in the hemoglobin level in the blood. The light is less than 5mW in power, so the use of the device is harmless to the user. It is intended for use by researchers to monitor in real-time the functionality of the brain during cognitive activities.
