Gowerlabs' extensive research experience has resulted in a range of fNIRS headgear options. We work closely with our users to design and develop bespoke headgear solutions that meet the specific demands of their research programmes.
fNIRS headgear must be comfortable, reliable and adaptable. At Gowerlabs, our headgear solutions come in two principle styles.
The first is based on EASYCAP caps (EASYCAP GmbH, Germany): a flexible, anatomically registered head-cap system originally developed for EEG research. EASYCAP caps are available in a wide range of sizes and can be used with all ages, from newborn infants to adults. The caps are comfortable, washable, and easy-to-apply with the Gowerlabs NTS Optical Imaging System. Because they are designed around the EEG 10-20 coordinate system, these caps also facilitate the direct spatial registration of fNIRS measurements with the cortical anatomy. More information about EASYCAP caps can be found here.
The second format is available via our partners at the Centre for Brain and Cognitive Development (CBCD, also known as Babylab) at Birkbeck, University of London. Babylab designs and manufactures fNIRS headgear for infants and toddlers based on their extensive experience applying Gowerlabs' fNIRS technology to study cognitive development. More information about the CBCD/Babylab can be found here. For more information about the CBCD fNIRS headgear please see the PDF below.
Infant Fibre Bundles
Gowerlabs infant fibre bundles are light-weight and flexible glass fibre bundles that provide excellent optical coupling and transmission. Each infant bundle has a flat subject interface to minimise the pressure applied to the scalp and ensure the subject remain comfortable during each fNIRS study.
Gowerlabs Infant Fibre Bundles can be used in conjunction with the EASYCAP or CBCD infant headgear systems.
Adult Fibre Bundles
Gowerlabs adult fibres bundles have identical properties to our Infant Fibre Bundles but include extra features to improve fNIRS signal quality in the presence of thicker hair.
Each bundle is coupled into an adaptor that fixes into the EASYCAP system. The bundles can be easily removed from these adaptors during set-up to allow hair to be combed out from under the fibre to maximise fNIRS signal quality. Our adult fibre bundles also have a slight protrusion at the subject interface that allows any remaining hair to be pushed aside upon insertion, and a foam coupling surface to ensure subject comfort.
In recent years, research has shown that short-separation fNIRS channels can be used to significantly improve the accuracy and reliability of fNIRS measurements. The flexibility of the Gowerlabs NTS Optical Imaging System allows users to incorporate multiple short-separations measurements in to their array design, resulting in higher-quality fNIRS data and more accurate interpretation.
