- Localization of seizure onset zone with epilepsy propagation networks . . .
Conclusion Compared to seizure propagation networks or high-frequency oscillatory propagation networks alone, the combined epilepsy propagation network based on graph convolutional networks was more strongly related with the possible epileptogenic brain region represented by the clinically diagnosed seizure onset zone
- How important is the seizure onset zone for seizure dynamics?
Results A high variability of temporal evolution of node importance was observed, both intra- and interindividually Nevertheless, nodes near and far off the seizure onset zone (SOZ) were rated as most important for seizure dynamics more often (65% of cases) than nodes from within the SOZ (35% of cases)
- Characterizing Hippocampal Oscillatory Signatures Underlying Seizures . . .
Temporal Lobe Epilepsy (TLE) is a neurological condition characterized by focal brain hyperexcitability, resulting in abnormal neuronal discharge and uncontrollable seizures The hippocampus, with its inherently highly synchronized firing patterns and relatively high excitability, is prone to epileptic seizures, and it is usually the focus of TLE
- Systematic review of seizure-onset patterns in stereo . . .
Lastly, for studies investigating the association between SOPs and surgical outcome with at least one year of postoperative follow-up, we extracted tables containing demographic information, such as patient age, sex, age at epilepsy onset (if available), the number of operated patients, the number of seizure-free patients postoperatively, and
- The high frequency oscillations in the amygdala, hippocampus, and . . .
Abstract The mesial temporal lobe epilepsy (MTLE) seizures are believed to originate from medial temporal structures, including the amygdala, hippocampus, and temporal cortex Thus, the seizures onset zones (SOZs) of MTLE locate in these regions
- Two Seizure-Onset Types Reveal Specific Patterns of High-Frequency . . .
Here, we recorded from the hippocampal CA3 subfield, subiculum, entorhinal cortex, and dentate gyrus to quantify the occurrence of ripples (80–200 Hz) and fast ripples (250–500 Hz) during low-voltage fast-onset (LVF) and hypersynchronous-onset (HYP) seizures in the rat pilocarpine model of temporal lobe epilepsy
- Seizure semiology, localization, and the 2017 ILAE seizure . . .
It is a crucial complement to the electroencephalographic description of seizures in the diagnosis and management of epilepsy By definition, semiology arises from activation of the symptomogenic zone (SZ), which may or may not harbor the seizure onset zone (SOZ) [3] 3
- Localizing epileptogenic zones with high-frequency . . . - Seizure
Epilepsy is a serious, chronic neurological disorder that disrupts the normal activity of neurons in the brain During seizure onset, the patient may be injured or even in a life-threatening emergency, which brings great psychological pressure and difficulties in work and life to the patient For patients with drug-resistant epilepsy, epilepsy surgery can effectively treat seizures The
