Operation Manual
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.
