EEG–fMRI mapping of asymmetrical delta activity in a patient with refractory epilepsy is concordant with the epileptogenic region determined by intracranial EEG [PDF]

, 2006
We studied a patient with refractory focal epilepsy using continuous EEG-correlated fMRI. Seizures were characterized by head turning to the left and clonic jerking of the left arm, suggesting a right frontal epileptogenic region.

Structural Eigenmodes of the Brain to Improve the Source Localization of EEG: Application to Epileptiform Activity

Advanced Science, EarlyView.
Geometry and connectivity are complementary structures, which have demonstrated their ability to represent the brain's functional activity. This study evaluates geometric and connectome eigenmodes as biologically informed constraints for EEG source localization.

Juvenile idiopathic epilepsy in Egyptian Arabian foals, a potential animal model of self‐limited epilepsy in children

Journal of Veterinary Internal Medicine
Background Juvenile idiopathic epilepsy (JIE) is categorized as a generalized epilepsy. Epilepsy classification entails electrocortical characterization and localization of epileptic discharges (ED) using electroencephalography (EEG).

Monitoring Migraine Cycle Dynamics with an Easy-to-Use Electrophysiological Marker—A Pilot Study

Sensors, 2018
Migraine attacks can cause significant discomfort and reduced functioning for days at a time, including the pre-ictal and post-ictal periods. During the inter-ictsal period, however, migraineurs seem to function normally.

Pattern Recognition in Epileptic EEG Signals via Dynamic Mode Decomposition

Mathematics, 2020
In this paper, we propose a new method based on the dynamic mode decomposition (DMD) to find a distinctive contrast between the ictal and interictal patterns in epileptic electroencephalography (EEG) data.

Early Seizure Detection with an Energy-Efficient Convolutional Neural Network on an Implantable Microcontroller

, 2018
Implantable, closed-loop devices for automated early detection and stimulation of epileptic seizures are promising treatment options for patients with severe epilepsy that cannot be treated with traditional means.

Features of aura in paediatric migraine diagnosed using the ICHD 3 beta criteria [PDF]

, 2017
Background In children and adolescents, the prevalence rate of migraine with aura is 1.6%. Few studies concerning migraine with aura features in paediatric population have been reported.

Ictal visual hallucinations and post-ictal hemianopia with anosognosia

Seizure, 2000
We report the case history of an adult who developed seizures with nearly pure visual symptoms due to an occipital vascular lesion. The seizures were characterized by elementary visual hallucinations in the right visual field. Interictally, a dense homonymous hemianopia was demonstrated in the clinical examination and by using perimetry, but was not ...

Brain‐Adhesive Bioelectronics With Shape‐Morphable and Biodegradable Properties for Stable Brain Signal Monitoring

Advanced Science, EarlyView.
A brain‐adhesive sensor (B‐Sensor) was developed by integrating a self‐healing biodegradable elastomer, a tissue‐adhesive hydrogel, and molybdenum electrodes. The B‐Sensor adheres to brain tissue, conforms to cortical curvatures, and maintains stable electrical performance over the intended period for reliable recording of spatiotemporal brain activity

Network Properties Revealed during Multi-Scale Calcium Imaging of Seizure Activity in Zebrafish. [PDF]

, 2019
Seizures are characterized by hypersynchronization of neuronal networks. Understanding these networks could provide a critical window for therapeutic control of recurrent seizure activity, i.e., epilepsy.
