WebJan 20, 2024 · Resting-state fMRI data were examined through static and dynamic functional connectivity (dFC) analyses, constructing cortico-striato-thalamo-cerebellar networks. Network patterns were compared between groups, and were correlated to epilepsy duration. WebResting‐state fMRI works on the assumption that the degree of synchrony between time‐varying blood‐oxygenation level‐dependent (BOLD) signals from spatially distinct brain regions indicates the strength of a functional connection (termed functional connectivity) [Beckmann et al., 2005; Fox and Raichle, 2007]. Most current approaches to ...
