The human brain is organized as a highly complex network in which regions can be represented as structurally interconnected and functionally synchronized networks. As a result, the theory of complex networks has recently been employed to investigate brain function during the resting state with functional Magnetic Resonance Imaging (fMRI). In addition to fMRI, Near-infrared Spectroscopy (NIRS) is another neuroimaging technique, highlighted because of its portability, low cost, and high temporal resolution. NIRS benefits from an "optical window" - in which near-infrared light is less absorbed - to estimate human brain's physiology information. Although functional connectivity has been studied with NIRS, a complex approach has never been employed to understand the fundamental characteristics of spontaneous brain activity in NIRS data. Thus, this project aims to investigate the brain functional connectivity during resting state with NIRS experiments and a promising approach grounded in statistical physics. (AU)
