Resting state cortical electroencephalographic rhythms in covert hepatic encephalopathy and Alzheimer's disease [PDF]

open access: yes, 2013
Patients suffering from prodromal (i.e., amnestic mild cognitive impairment, aMCI) and overt Alzheimer's disease (AD) show abnormal cortical sources of resting state electroencephalographic (EEG) rhythms.

Altered whole-brain resting-state functional connectivity and brain network topology in typhoon-related post-traumatic stress disorder

open access: yesTherapeutic Advances in Psychopharmacology, 2023
Background: Altered resting-state functional connectivity has been found in patients with post-traumatic stress disorder (PTSD). However, the alteration of resting-state functional connectivity at whole-brain level in typhoon-traumatized individuals with

Test–Retest Reliability of Synchrony and Metastability in Resting State fMRI

open access: yesBrain Sciences, 2021
In recent years, interest has been growing in dynamic characteristic of brain signals from resting-state functional magnetic resonance imaging (rs-fMRI). Synchrony and metastability, as neurodynamic indexes, are considered as one of methods for analyzing

EEG Frequency Bands in Psychiatric Disorders: A Review of Resting State Studies

open access: yesFrontiers in Human Neuroscience, 2019
A significant proportion of the electroencephalography (EEG) literature focuses on differences in historically pre-defined frequency bands in the power spectrum that are typically referred to as alpha, beta, gamma, theta and delta waves.

Resting-state Networks in Tinnitus

open access: yesClinical Neuroradiology, 2022
AbstractChronic subjective tinnitus is the constant perception of a sound that has no physical source. Brain imaging studies show alterations in tinnitus patients’ resting-state networks (RSNs). This scoping review aims to provide an overview of resting-state fMRI studies in tinnitus, and to evaluate the evidence for changes in different RSNs.

Disruption of brain connectivity in acute stroke patients with early impairment in consciousness

open access: yesFrontiers in Psychology, 2014
Impairment in consciousness is common in acute stroke patients and is correlated with the clinical outcome after stroke. The underlying mechanism is not completely understood, with little known about brain activity and connectivity changes in acute ...

Effects of Sub-threshold Transcutaneous Auricular Vagus Nerve Stimulation on Cingulate Cortex and Insula Resting-state Functional Connectivity

open access: yesFrontiers in Human Neuroscience, 2022
Transcutaneous auricular vagus nerve stimulation (taVNS), a non-invasive alternative to vagus nerve stimulation (VNS) with implantable devices, has shown promise in treating disorders such as depression, migraine, and insomnia. Studies of these disorders

Functional connectivity between the amygdala and subgenual cingulate gyrus predicts the antidepressant effects of ketamine in patients with treatment‐resistant depression

open access: yesNeuropsychopharmacology Reports, 2021
Aim Approximately one‐third of patients with major depressive disorder develop treatment‐resistant depression. One‐third of patients with treatment‐resistant depression demonstrate resistance to ketamine, which is a novel antidepressant effective for ...

Rapidly spreading seizures arise from large-scale functional brain networks in focal epilepsy

open access: yesNeuroImage, 2021
It remains unclear whether epileptogenic networks in focal epilepsy develop on physiological networks. This work aimed to explore the association between the rapid spread of ictal fast activity (IFA), a proposed biomarker for epileptogenic networks, and ...

Resting-State Cerebello-Cortical Dysfunction in Parkinson's Disease

open access: yesFrontiers in Neurology, 2021
Purpose: Recently, the cerebellum's role in Parkinson's disease (PD) has been highlighted. Therefore, this study sought to test the hypothesis that functional connectivity (FC) between cerebellar and cortical nodes of the resting-state networks ...
