High-frequency oscillations and seizure generation in neocortical epilepsy.
Neocortical seizures are often poorly localized, explosive and widespread at onset, making them poorly amenable to epilepsy surgery in the absence of associated focal brain lesions. We describe, for the first time in an unselected group of patients with neocortical epilepsy, the finding that high-frequency (60-100 Hz) epileptiform oscillations are highly localized in the seizure onset zone, bot...
متن کاملDynamic Network Drivers of Seizure Generation, Propagation and Termination in Human Neocortical Epilepsy
The epileptic network is characterized by pathologic, seizure-generating 'foci' embedded in a web of structural and functional connections. Clinically, seizure foci are considered optimal targets for surgery. However, poor surgical outcome suggests a complex relationship between foci and the surrounding network that drives seizure dynamics. We developed a novel technique to objectively track se...
متن کاملSeizure Control of Current Shunt on Rats with Temporal Lobe Epilepsy and Neocortical Epilepsy
PURPOSE To examine the effects of current shunt on rats with temporal lobe epilepsy and neocortex epilepsy. EXPERIMENTAL DESIGN A kainic acid (KA)-induced model of temporal lobe seizure and a penicillin-induced model of neocortical partial seizure were used in this study. Rats of each model were randomly allocated into two groups: control and model groups. The model group was further divided ...
متن کاملPartial epilepsy presenting as focal atonic seizure: A case report
A case of atonic seizures localized to the frontal lobe by video-EEG monitoring is reported. The patient is a 38-year-old female with intractable atonic seizures characterized by abrupt onset of facial grimacing and a slow head drop. The onset of atonic seizures was about 6 years before presentation. Video-EEG monitoring showed that her atonic seizures were emanating from the right frontal head...
متن کاملNonlinear EEG analysis in epilepsy: its possible use for interictal focus localization, seizure anticipation, and prevention.
Several recent studies emphasize the high value of nonlinear EEG analysis particularly for improved characterization of epileptic brain states. In this review the authors report their work to increase insight into the spatial and temporal dynamics of the epileptogenic process. Specifically, they discuss possibilities for seizure anticipation, which is one of the most challenging aspects of epil...
