The human brain has about 100 billion neurons. Humans take in the information associated with sight, hearing, touch, smell, and taste from sensory organs (eyes, ears, etc.) and convert this information to electrical signals which are then sent to the brain. Neurons in the brain process this information through mutual exchange of the signals to determine the next action. During this process, oxygenated hemoglobin (oxyHb) supplies oxygen via capillary vessels. NIRS technology can analyze the functional localization of the brain by measuring this reaction in real time using near infrared light.


Accepts up to 40 sets––2.5 times more than before (142 channels max.). Spatial resolution doubled for high-density measurements. Captures rapid cerebral blood flow signals in just 6 ms (previously 25 ms). Three semiconductor laser wavelengths capture more accurate data. A photomultiplier tube captures the weakest cerebral signals. Flexible Adjustable Surface Holder (FLASH) supports more stable measurements. Select from the wide range of holders, which are easily customizable.
