fNIRS avoids electrical artifacts and works with implanted devices where fMRI and EEG fail

Evidence

For studying language areas in the brain in CI users, fNIRS offers some advantages over other imaging methods: compared to PET it is non-invasive; in contrast to fMRI it can be used easily with implanted devices, is silent, and is more robust to head movements; compared to EEG/MEG it has much greater spatial resolution, and in CI users is free from electrical or magnetic artifacts from the device or the stimuli. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4273
