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 ...

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 ...

Effective Connectivity-based Unsupervised Channel Selection Method for Electroencephalography [PDF]

Journal of Medical Signals and Sensors
Background: Analyzing neural data such as electroencephalography (EEG) data often involves dealing with high-dimensional datasets, where not all channels provide equally meaningful information.

Functional and Effective Connectivity: A Review [PDF]

Brain Connectivity, 2011
Over the past 20 years, neuroimaging has become a predominant technique in systems neuroscience. One might envisage that over the next 20 years the neuroimaging of distributed processing and connectivity will play a major role in disclosing the brain's functional architecture and operational principles.

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 ...

Abnormalities of EEG Functional Connectivity and Effective Connectivity in Children with Autism Spectrum Disorder

Brain Sciences, 2023
Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental disorder that interferes with normal brain development. Brain connectivity may serve as a biomarker for ASD in this respect. This study enrolled a total of 179 children aged 3−10 years (

Adaptation modulates effective connectivity and network stability [PDF]

Frontiers in Computational Neuroscience
The brain is a highly recurrent, nonlinear network hypothesized to remain near the edge of chaos for optimal performance. Excitation and inhibition must be balanced precisely within every neuron to ensure a consistent level of dynamical stability and ...

Classification of Schizophrenia by Combination of Brain Effective and Functional Connectivity

Frontiers in Neuroscience, 2021
At present, lots of studies have tried to apply machine learning to different electroencephalography (EEG) measures for diagnosing schizophrenia (SZ) patients. However, most EEG measures previously used are either a univariate measure or a single type of

Comparing effective and functional connectivity

Scientific Reports
Information processing in the brain is thought to result from the coordination of large-scale neuronal activity. However, this activity occurs within fine neural circuits.

Visualizing effective connectivity in the human brain

Brain Stimulation
Abstract To enhance mechanistic understanding of effective connectivity in the human brain, we created a tool that links high-temporal resolution transcranial magnetic stimulation electroencephalography (TMS-EEG) with high-spatial resolution diffusion MRI.
