Independent component analysis of interictal fMRI in focal epilepsy: comparison with general linear model-based EEG-correlated fMRI [PDF]

open access: yes, 2007
The general linear model (GLM) has been used to analyze simultaneous EEG–fMRI to reveal BOLD changes linked to interictal epileptic discharges (IED) identified on scalp EEG. This approach is ineffective when IED are not evident in the EEG.

Creutzfeldt-Jakob disease a case report, with special attention to the electroencephalogram in this disorder and to its possible relationships to kuru, scrapie and «mad cow disease»

open access: yesArquivos de Neuro-Psiquiatria, 1993
A case of Creutzfeldt-Jakob disease in a 58-year-old Brazillian cattle rancher and businessman is presented. The EEG was normal, which is consistent with the fact that it was made during the first half of his illness; in a later stage suppression of ...

Electrodiagnostic artifacts due to neurostimulation devices for drug resistant epilepsy

open access: yesEpilepsy & Behavior Reports, 2022
Background: Neurostimulation devices including vagus nerve stimulation (VNS), deep brain stimulation (DBS), and responsive neurostimulation (RNS) are approved therapeutic options for drug resistant epilepsy (DRE).

Cortical sources of resting state EEG rhythms are sensitive to the progression of early stage Alzheimer's disease [PDF]

open access: yes, 2013
Cortical sources of resting state electroencephalographic (EEG) rhythms are abnormal in subjects with Alzheimer's disease (AD). Here we tested the hypothesis that these sources are also sensitive to the progression of early stage AD over the course of ...

EEG biomarker candidates for the identification of epilepsy

open access: yesClinical Neurophysiology Practice, 2023
Electroencephalography (EEG) is one of the main pillars used for the diagnosis and study of epilepsy, readily employed after a possible first seizure has occurred.

Continuous EEG source imaging enhances analysis of EEG-fMRI in focal epilepsy

open access: yes, 2010
Introduction: EEG-correlated fMRI (EEG-fMRI) studies can reveal haemodynamic changes associated with Interictal Epileptic Discharges (IED). Methodological improvements are needed to increase sensitivity and specificity for localising the epileptogenic ...

A statistical technique for measuring synchronism between cortical regions in the EEG during rhythmic stimulation [PDF]

open access: yes, 2001
The coherence function has been widely applied in quantifying the degree of synchronism between electroencephalogram (EEG) signals obtained from different brain regions.

The spatio-temporal mapping of epileptic networks: Combination of EEG–fMRI and EEG source imaging

open access: yes, 2009
Simultaneous EEG–fMRI acquisitions in patients with epilepsy often reveal distributed patterns of Blood Oxygen Level Dependant (BOLD) change correlated with epileptiform discharges.

Simultaneous intracranial EEG and fMRI of interictal epileptic discharges in humans [PDF]

open access: yes, 2011
Simultaneous scalp EEG–fMRI measurements allow the study of epileptic networks and more generally, of the coupling between neuronal activity and haemodynamic changes in the brain.
