AI Overview
fNIRS fiber optic cables are flexible, specialized optical fiber bundles designed to deliver and collect near-infrared light (600–900 nm) to measure cerebral cortex oxygenation. They connect light sources to sensors placed on the scalp, often utilizing high-transmission Schott or quartz glass to ensure low signal loss during brain imaging studies.
Key Aspects of fNIRS Fiber Optic Cables
- Function: They transmit low levels of light (<0.4W/cm²) to source positions on the head to detect oxy- and deoxyhemoglobin changes.

What is fNIRS technology?
Functional near-infrared spectroscopy (fNIRS) is a portable, non-invasive, brain imaging technology that uses low levels of non-ionizing light to record changes in cerebral blood flow in the brain through optical sensors placed on the surface of the scalp.

What is the cost of fNIRS equipment?
We have designed single-channel fNIRS hardware and accompanying data collection software (for Android phones and Windows/Mac Computers) that can be assembled for approximately $215. In addition to collecting fNIRS signals, the system can reduce artifacts due to motion and other superficial signals [10], [11], [13].

What are the limitations of fNIRS?
fNIRS can only measure cortical activity due to its limited depth penetration. It cannot provide information about subcortical structures or deeper brain regions. This is a significant limitation when studying cognitive processes that involve these areas.
