As fNIRS measures brain activity based on light, no interference occurs when combined with neurostimulation methods that use magnetic (TMS) or direct current stimulation (tDCS). Moreover, this makes fNIRS an ideal brain imaging modality in research where the brain has to be stimulated and local activity simultaneously quantified.
There are multiple brain imaging modalities available nowadays. But how do you decide which modality fits your research best? fNIRS is known for the fact that it is non-invasive, portable, and has a good spatial resolution.
VR is a simulated experience that can be sometimes almost indistinguishable from real-world experiences. Since the fNIRS devices produced by Artinis can be easily combined with VR headsets, researchers have utilized this by assessing brain activity while their subjects are immersed in a VR world.
