[0001] The utility model relates to the technical field of near-infrared brain imagers, in particular to a wearable functional near-infrared brain imager. Background Art

[0002] The near-infrared photoencephalography is an instrument used in the field of psychology. Photobiomodulation, the use of red to near-infrared light on body tissue, can improve central and peripheral neuronal function and survival in health and disease. These improvements are thought to stem primarily from the effects of photobiomodulation on mitochondrial and non-mitochondrial mechanisms in a range of different cell types, including neurons. With increasing momentum, recent reports using a range of biological measures have shown that transcranial photobiomodulation can affect brain, particularly cortical activity, and photobiomodulation has been shown to not only affect the functional activity of neurons throughout the brain, but also improve their survival to injury or disease.
