Abstract: To date,measuring the neural activity of speech processing in adults and children after cochlear implantation has been a great challenge because conventional neuroimaging techniques are limited by the magnetic properties of cochlear implants.Functional near-infrared spectroscopy(fNIRS)is a non-invasive imaging technique for neuroimaging the brain compatible with implanted devices and unaffected by electrical artifacts.fNIRS is suitable for measuring the neural activity of speech processing in adult and pediatric cochlear implant recipients and can better identify and interpret cortical responses.The purpose of this paper is to summarize the use of fNIRS as a tool to measure the neural activation level of speech processing in cochlear implant recipients for different types of speech stimuli,and thus to provide a clinical and objective basis for the assessment of auditory speech rehabilitation and the development of rehabilitation programs for implant recipients.
