Neuronal dynamics enable the functional differentiation of resting state networks in the human brain

Description
Summary:Intrinsic brain activity is organized in spatial–temporal patterns, called resting‐state networks (RSNs), exhibiting specific structural–functional architecture. These networks presumably reflect complex neurophysiological processes and have a central role in distinct perceptual and cognitive functions. In this work, we propose an innovative approach for characterizing RSNs according to their underlying neural oscillations. We investigated specific electrophysiological properties, including spectral features, fractal dimension, and entropy, associated with eight core RSNs derived from high‐density electroencephalography (EEG) source‐reconstructed signals. Specifically, we found higher synchronization of the gamma‐band activity and higher fractal dimension values in perceptual (PNs) compared with higher cognitive (HCNs) networks. The inspection of this underlying rapid activity becomes of utmost importance for assessing possible alterations related to specific brain disorders. The disruption of the coordinated activity of RSNs may result in altered behavioral and perceptual states. Thus, this approach could potentially be used for the early detection and treatment of neurological disorders.
