Research progress of functional near infrared imaging in the field of drug addiction

Abstract

Functional near-infrared spectroscopy (fNIRS) is a new non-invasive brain near-infrared spectroscopy technology, which has the advantages of low cost, portability and real-time continuous dynamic capture, it is widely used in different clinical situations. In the field of addiction, fNIRS can be used in assessment studies of neurocognitive abilities and intervention effects of different addictive behaviors, in which neurobiological indicators associated with fNIRS can be used as potential biomarkers to assess the level of addiction; Or as an indicator of addiction-related cravings. In this paper, we reviewed and analyzed the literature of fNIRS and its application in the field of drug addiction from the aspects of cognitive function evaluation and therapeutic effect evaluation related to addiction behavior, provide reference for future research.
