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 ...

THE RELATIONSHIP BETWEEN THE DEFAULT MODE RESTING STATE NEURAL NETWORK, RESPIRATORY SINUS ARRHYTHMIA, AND SELF-FOCUSED COGNITION: AN EMPIRICAL ANALYSIS [PDF]

, 2013
Functional activity within the default mode resting state neural network (RSNN) and the resting respiratory sinus arrhythmia (RSA) may represent an integrated neural and peripheral cardiovascular index of the baseline, resting state in humans.

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 ...

Early neurocognitive outcomes following SEEG with radiofrequency thermocoagulation

Epilepsia Open, EarlyView.
Abstract Objective Characterization of early neuropsychological outcomes following SEEG with radiofrequency thermocoagulation (RFTHC) is essential to guide patient expectations around return to work, study, and caregiving. The current study aimed to describe the early neurocognitive sequelae of SEEG.

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 ...

Analysis of individualized brain–gut association networks and transcriptional patterns in major depressive disorder

Interdisciplinary Medicine, EarlyView.
Individualized brain–gut association networks suggest potential neuropathological mechanisms in MDD and MDDSI. Multilevel brain–gut association changes involving HSV‐1 and inflammation may be relevant to MDD, whereas alterations related to insulin metabolism may play a potential role in the neuropathological mechanisms of MDDSI.

Detecting spatiotemporal nonlinear dynamics in resting state of human brain based on fMRI datasets

, 2008
In this work, a nonlinear dynamics method, coupled map lattices, was applied to functional magnetic resonance imaging (fMRI) datasets to examine the spatiotemporal properties of resting state blood oxygen level-dependent (BOLD) fluctuations ...
