Using Functional Neuroinfrared Spectroscopy for Assistive Communication

Functional neuroinfrared spectroscopy (F-NERS) is a brain imaging technology that could be a potential assistive device for individuals who have lost the ability to communicate due to brain damage. Unlike an MRI scanner, F-NERS is a more practical option as it uses infrared light to measure blood flow in the brain. By shining different wavelengths of infrared light through a person's skull, F-NERS can measure the blood oxygenation level, which is similar to the fMRI signal. Although it is not currently a consumer device, F-NERS has the potential to be used at home in the future.
