Effective Connectivity in Depression [PDF]
Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, 2018 Resting-state functional connectivity reflects correlations in the activity between brain areas, whereas effective connectivity between different brain areas measures directed influences of brain regions on each other. Using the latter approach, we compare effective connectivity results in patients with major depressive disorder (MDD) and control ...

Dynamic effective connectivity
NeuroImage, 2020 Metastability is a key source of itinerant dynamics in the brain; namely, spontaneous spatiotemporal reorganization of neuronal activity. This itinerancy has been the focus of numerous dynamic functional connectivity (DFC) analyses – developed to ...

Structurally constrained effective brain connectivity
NeuroImage, 2021 The relationship between structure and function is of interest in many research fields involving the study of complex biological processes. In neuroscience in particular, the fusion of structural and functional data can help to understand the underlying ...

Asymmetric high-order anatomical brain connectivity sculpts effective connectivity [PDF]
Network Neuroscience, 2020 Bridging the gap between symmetric, direct white matter brain connectivity and neural dynamics that are often asymmetric and polysynaptic may offer insights into brain architecture, but this remains an unresolved challenge in neuroscience.

Effective connectivity during autobiographical memory search [PDF]
Brain and Behavior, 2020 Introduction We used dynamic causal modeling (DCM) to examine effective connectivity during cued autobiographical memory (AM) search in a left‐hemispheric network consisting of six major regions within the large network of brain regions recruited during ...

Effective connectivity in autism [PDF]
Autism Research, 2019 The aim was to go beyond functional connectivity, by measuring in the first large‐scale study differences in effective, that is directed, connectivity between brain areas in autism compared to controls. Resting‐state functional magnetic resonance imaging was analyzed from the Autism Brain Imaging Data Exchange (ABIDE) data set in 394 people with autism
