Structurally constrained effective brain connectivity

open access: yesNeuroImage, 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

open access: yesBrain 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 (

Dynamic effective connectivity

open access: yesNeuroImage, 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-based Unsupervised Channel Selection Method for Electroencephalography [PDF]

open access: yesJournal 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.

Networks underpinning emotion: A systematic review and synthesis of functional and effective connectivity

open access: yesNeuroImage, 2021
Existing models of emotion processing are based almost exclusively on brain activation data, yet make assumptions about network connectivity. There is a need to integrate connectivity findings into these models.We systematically reviewed all studies of ...

Adaptation modulates effective connectivity and network stability [PDF]

open access: yesFrontiers 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 ...

Comparing effective and functional connectivity

open access: yesScientific 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.

Structural and effective connectivity in focal epilepsy [PDF]

open access: yesNeuroImage: Clinical, 2018
Patients with medically-refractory focal epilepsy may be candidates for neurosurgery and some may require placement of intracranial EEG electrodes to localise seizure onset.

EEG effective connectivity during the first year of life mirrors brain synaptogenesis, myelination, and early right hemisphere predominance

open access: yesNeuroImage, 2022
Introduction: The maturation of electroencephalogram (EEG) effective connectivity in healthy infants during the first year of life is described. Methods: Participants: A cross-sectional sample of 125 healthy at-term infants, from 0 to 12 months of age ...

Effective connectivity in autism [PDF]

open access: yesAutism 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
