Abstract: Characterizing functional brain connectivity using resting functional magnetic resonance imaging (fMRI) is challenging due to the relatively small Blood-Oxygen-Level Dependent contrast and low signal-to-noise ratio. Denoising using surface-based Laplace-Beltrami (LB) or volumetric Gaussian filtering tends… read more here.

DOI: 10.1016/j.media.2022.102366
Abstract: Highlights • MAGE is multi-dynamic in that it models temporal fluctuations in FC independently from fluctuations in the mean of the activity.• MAGE reveals stronger changes in FC over time than single-dynamic approaches, such as… read more here.

DOI: 10.1162/netn_a_00116
Abstract: Abstract The brain is a complex, multiscale dynamical system composed of many interacting regions. Knowledge of the spatiotemporal organization of these interactions is critical for establishing a solid understanding of the brain’s functional architecture and… read more here.
