Static and Dynamic Resting-State fMRI Connectivity Show Frequency-Resolved Associations With Intracranial EEG Connectivity. [PDF]

open access: yesHum Brain Mapp
Resting‐state functional MRI (fMRI) connectivity reflects both stable electrophysiological coupling and frequency‐specific neural dynamics. Using simultaneous intracranial EEG–fMRI in 48 epilepsy patients, we show that static connectivity aligns with beta/low‐gamma coupling, whereas dynamic connectivity tracks alpha and beta fluctuations.

Absence seizures: Update on signaling mechanisms and networks

open access: yesEpilepsia 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 ...

A spatially constrained low-rank matrix factorization for the functional parcellation of the brain

open access: yes, 2014
We propose a new matrix recovery framework to partition brain activity using time series of resting-state functional Magnetic Resonance Imaging (fMRI). Spatial clusters are obtained with a new low-rank factorization algorithm that offers the ability to ...

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

open access: yesEpilepsia 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 ...

Resting-state functional connectivity of orthographic networks in acquired dysgraphia

open access: yesFrontiers in Psychology, 2015
Introduction. While task-based fMRI has been used extensively to study the functional neural networks that instantiate cognitive functions, there is increasing interest in analyzing the activity of the brain while it is not performing a task – in the ...

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

open access: yesEpilepsia 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.

Integration of resting state functional MRI into clinical practice - A large single institution experience.

open access: yesPLoS ONE, 2018
Functional magnetic resonance imaging (fMRI) is an important tool for pre-surgical evaluation of eloquent cortex. Classic task-based paradigms require patient participation and individual imaging sequence acquisitions for each functional domain that is ...

Disrupted cerebellar networks in uncontrolled focal to bilateral tonic–clonic seizures

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Focal to bilateral tonic–clonic seizures (FBTC) are associated with significant morbidity and an elevated risk of sudden unexpected death in epilepsy (SUDEP). The cerebellum has been implicated in modulating the frequency and severity of tonic–clonic seizures.
