Critical dynamics of cortical excitability and hippocampal seizures

Gregory Lepeu, Ellen van Maren, Antoine Adamantidis, Timothée Proix, Maxime Baud · FENS Forum 2024

The sudden emergence of dangerous seizures is the defining feature of epilepsy, but how and when the brain changes dynamics remains enigmatic. From the perspective of dynamical systems theory, such critical transitions occur upon inconspicuous perturbations in highly interconnected systems presenting positive feedback loops and can be modeled as mathematical bifurcations between alternative regimes. Here, we sought to characterize dynamical signatures of impending seizures. We systematically verified the predictions of the model called ‘Epileptor’ that captures seizure dynamics in five differe

IL-1-PIP3 signal cascade mediates epilepsy and sleep disturbances

Shu-Hui Huang, Pei-Lu Yi, Fang-Chia Chang · FENS Forum 2024

Aims: Interleukin-1β (IL-1β) in the central nervous system initiates a PI3K signaling cascade, involving crucial membrane phospholipids phosphatidylinositol (4,5)-bisphosphate (PIP2) and phosphatidylinositol (3,4,5)-trisphosphate (PIP3). While PIP2's role in epileptogenesis is known, our study investigates the unclear role of PIP3 using PTZ-induced epileptic mice, exploring its impact on epileptogenesis and associated sleep disruptions. Methods: Our hypothesis proposed a pivotal role for PIP3 in the molecular mechanism of seizures. We intraperitoneal administered low dose of PTZ once every two
