Abstract

It has been known that in human brain, prefrontal cortex intensively controls the cognitive processes. In this study, functional near infrared spectroscopy (fNIRS) system has been used which is a promising method and has a relatively easier application. The aim of this study is to measure the prefrontal activity of the human brain using a Go-Nogo paradigm which is a common task to measure inhibitory activity in neuroscience field. We have investigated the inhibitory activity triggered by a Go-Nogo paradigm for the first time using fNIRS method with general linear model (GLM) analysis.
