Localisation in focal epilepsy: a practical guide

WebNov 2, 2024 · To better understand epileptic activity, several research groups have developed connectivity- and propagation-based network measures to describe the course of epilepsy activity in patients (Bartolomei et al., 2013, Kramer and Cash, 2012, Malinowska et al., 2014). However, the intricacy of epilepsy networks makes it difficult to develop a ... WebKey findings: The ictal HFOs began in the sensory cortex and appeared concomitantly with the sensory aura. They then propagated to the motor cortex at the same time that focal motor symptoms evolved. As the seizure progressed, the ictal HFOs spread or reverberated in the rolandic region. suspekt medizin https://calderacom.com
