Mild traumatic brain injury (mTBI) is a common condition that affects many people around the world. While some cases resolve without long-term side effects, others have to live with permanent disabilities such as learning difficulties, behavioral issues, and memory loss [1]. Conventional imaging techniques are unable to detect abnormalities in the brain of mTBI patients that have shown delayed functional response on neuropsychological evaluation. Therefore, the main objective of this study was to explore a novel analysis approach involving measurement of the temporal fractal nature of the resting state blood oxygen level depending (rsBOLD) signal
