In this study we used EEG-fMRI to investigate whether peri-ventricular nodular heterotopia (PNH) are connected to the seizure generating network in individuals initially diagnosed with absence seizures (AS) who were later found to have co-existent PN

Summary Purpose The aim of this study was to provide better spatiotemporal description of the brain activity observed during generalized spike-and-wave (GSW) discharges. Simultaneous electroencephalography and functional magnetic resonance imaging (E

MRI provides a powerful tool for studying the functional and structural connections in the brain non-invasively. The technique of functional connectivity (FC) exploits the intrinsic temporal correlations of slow spontaneous signal fluctuations to cha

Summary Purpose Functional imaging studies have identified a common network of brain regions that activate and deactivate during the generalised spike wave (GSW) discharges of childhood absence epilepsy (CAE). Functional connectivity within this netw

OBJECTIVES: We used EEG-fMRI to study epileptiform activity in a cohort of untreated children with typical absence seizures (AS). Our aim was to identify cortical and subcortical regions involved in spike and wave events and to explore the timing of

Simultaneous EEG and functional MRI (EEG-fMRI) studies of focal epileptiform spikes commonly use the canonical haemodynamic response function (HRF) to model the blood-oxygenation-level-dependent (BOLD) response to these events. Support for the use of

Recording the electroencephalogram (EEG) during functional magnetic resonance imaging (fMRI) permits the identification of haemodynamic changes associated with EEG events. However, subject motion within the MR scanner can cause unpredictable and frus

Patients with refractory temporal lobe epilepsy (refractory TLE) often have hippocampal sclerosis (HS). However, some HS patients have less-severe, drug-responsive epilepsy (mild TLE). We investigated the pattern of MR changes in these two HS groups.

One of the most significant impediments to high-quality EEG recorded in an MRI scanner is subject motion. Availability of motion artifact sensors can substantially improve the quality of the recorded EEG. In the study of epilepsy, it can also dramati

Resting state functional connectivity (rFC) is used to identify functionally related brain areas without requiring subjects to perform specific tasks. Previous work suggests that prior brain state, as determined by the activity engaged in immediately
