Detecting language network alterations in mild cognitive impairment using task‐based fMRI and resting‐state fMRI: A comparative study

Brain and Behavior
Objective The objective of this study was to investigate the functional changes associated with mild cognitive impairment (MCI) using independent component analysis (ICA) with the word generation task functional magnetic resonance imaging (fMRI) and ...

Neurovascular coupling in eye-open-eye-close task and resting state: Spectral correspondence between concurrent EEG and fMRI

NeuroImage
Neurovascular coupling serves as an essential neurophysiological mechanism in functional neuroimaging, which is generally presumed to be robust and invariant across different physiological states, encompassing both task engagement and resting state ...

Ventral anterior thalamic dysfunction distinguishes seizure generalization in temporal lobe epilepsy

Epilepsia, EarlyView.
Abstract Objective Focal‐to‐bilateral tonic–clonic seizures (FBTCS) in temporal lobe epilepsy (TLE) involve thalamocortical networks, yet the functional integrity and role of specific thalamic subregions in seizure generalization remain unclear. In this cross‐sectional study, we investigated whether thalamic subregion functional connectivity patterns ...

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Multi-timescale hybrid components of the functional brain connectome: A bimodal EEG-fMRI decomposition

Network Neuroscience, 2020
Concurrent electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) bridge brain connectivity across timescales. During concurrent EEG-fMRI resting-state recordings, whole-brain functional connectivity (FC) strength is spatially ...

Abnormal functional connectivity patterns in temporal lobe epilepsy—An international ENIGMA‐epilepsy study

Epilepsia Open, EarlyView.
Abstract Objectives Temporal lobe epilepsy (TLE) impacts multiple brain networks. Aberrant functional connectivity has been demonstrated in resting‐state networks (RSNs) that mediate higher brain functions in TLE. This study aimed to identify the reproducible patterns of altered functional connectivity in TLE in a large, international cohort through ...

Construct validation of a DCM for resting state fMRI

NeuroImage, 2015
Recently, there has been a lot of interest in characterising the connectivity of resting state brain networks. Most of the literature uses functional connectivity to examine these intrinsic brain networks. Functional connectivity has well documented limitations because of its inherent inability to identify causal interactions. Dynamic causal modelling (

Ten‐year cognitive outcomes following epilepsy surgery: Temporal lobectomy versus selective amygdalohippocampectomy

Epilepsia Open, EarlyView.
Abstract Objective This study aimed to assess long‐term memory outcomes in patients with temporal lobe epilepsy (TLE) who underwent anterior temporal lobectomy (ATL) or selective amygdalohippocampectomy (SAH), compared to nonoperated TLE over a 10‐year follow‐up period.

Disrupted Brain Structure and Function in Alzheimer's Disease Patients With Behavioral and Psychological Symptoms

iNew Medicine, EarlyView.
ABSTRACT Objective Behavioral and psychological symptoms of dementia (BPSD) are highly prevalent in Alzheimer’s disease (AD), but the underlying mechanisms are unclear. This study aims to elucidate the neuropathological mechanisms underlying BPSD by investigating gray matter volume (GMV) and brain connectivity in AD patients with and without BPSD ...

Evaluation of Multiband EPI Acquisitions for Resting State fMRI

PLOS ONE, 2015
Functional magnetic resonance imaging (fMRI) and particularly resting state fMRI (rs-fMRI) is widely used to investigate resting state brain networks (RSNs) on the systems level. Echo planar imaging (EPI) is the state-of-the-art imaging technique for most fMRI studies.
