FAQs
What is fNIRS?
Functional Near-Infrared Spectroscopy (fNIRS) leverages the transparency of human tissue to NIR light and the oxygenation-dependent properties of hemoglobin. By monitoring changes in oxyhemoglobin and deoxyhemoglobin concentrations at multiple wavelengths, is is possible to measure brain activity.
What is DOT?
Diffuse Optical Tomography (DOT) is an emerging approach that Gowerlabs is proud to have helped to pioneer. Our high density devices provide hundreds of channels, allowing you to produce three dimensional reconstructions of brain activity.
How many channels does LUMO have?
Traditional fNIRS devices are based on their channel count - the number of source-detector pairs available. We specialise in high-density technologies, providing hundreds of channels. We no longer use channels to describe our systems, instead we base it on coverage.
How do you deal with hair?
Although near-infrared light can travel well through the scalp, hair can interfere. We have specially designed light guides that comb through hair and maximise signal quality.
Is there a large data output?
Yes, but don’t let that put you off. More data means more accurate research, and enables 3D reconstruction. If data analysis is a concern, we offer research support packages to assist.
Why LUMO?
Since its inception, the application of fNIRS technology has been limited by low image resolution, uneven brain sensitivity, and the need to apply bulky optical fibres to the scalp of every subject. LUMO changes this.
