How NIRS is used in brain-computer interfaces

Imagine a person wearing a Brite and playing a demanding video game. This video game is difficult, and the mental workload is increasing drastically. Changes in blood volume, or hemodynamic changes, which are associated with the increase in workload is registered using the Brite. This blog will expand on how a NIRS-based BCI works and what researchers have made possible using NIRS-based BCI.

NIRS and connectivity measures: an Interview with Prof. Stephane Perrey

fNIRS, as a neuroimaging method, was introduced more than two decades ago. Innovation in equipment, tools, and methods based on related-neuroimaging methods is increasing thanks to several companies and academic laboratories. The use of fNIRS in future research practices will aid in advancing modern investigations of human brain function. Connectivity measures will contribute to the field of neuroscience and a multimodal imaging approach is likely required.

Combining the world of NIRS and EEG

EEG and fNIRS are complementary measuring techniques. EEG measures electrophysiological brain activation, that is the electromagnetic field created when neurons in the brain are firing. fNIRS measures the hemodynamic response, that is the change of oxygen in the blood when a brain region becomes active. By combining EEG and fNIRS, a more complete picture of brain activity is obtained: activation of neurons and energy demand of neurons.

3D Digitization and Co-Registration to the MNI brain template using OxySoft

How do we know that the most active channels are located over the brain region of interest and not somewhere else? Of course, an experienced researcher just knows where to place the optodes, but is that enough to convince a potential highly-critical reviewer or fellow scientist?
