| summary | We analyzed two large databases of resting state fMRI data (RSNs), and projected the results on task-based networks (TBNs) as referenced in large databases of fMRI activation studies. Results revealed that RSNs are organized into a remarkable architecture of two intertwined rings per hemisphere. The first ring (Visual-Sensorimotor-Auditory: VSA ring), relates in a continuous ensemble all cortical regions processing real-time information (sensory, motor and interspersed bimodal cortices). The second ring integrates distant parietal, temporal and frontal regions (PTF ring), lateral and medial, through a network of association fiber tracts, closing the ring and forming a functional continuity between areas performing multi-temporal processing (i.e., relating past, present, and future at different temporal scales): this ring relates brain regions involved in vital functions and biological rhythms, with regions involved in higher cognitive functions (episodic, working memory, language, social interpretations..). The two intertwined rings have large interfaces along precentral, superior temporal and intraparietal sulci. |
