[Organizers and chief editors] In: 5 th International Workshops, 5 th Jasper's Basic Mechanisms of the Epilepsies (BME) Workshops, Yosemite National Park, Calif. (March , ).; Noebels J, Delgado-Escueta A, Rossignol E. Book Section III: Genes and Network. Epileptogenesis is the gradual process by which a normal brain develops epilepsy. Epilepsy is a chronic condition in which seizures occur. These changes to the brain occasionally cause neurons to fire in a hyper-synchronous manner, known as a seizure. 2 Latent period. 3 Pathophysiology. Neural reorganization. Glutamate receptor activation.   The book discusses these challenges in the clinic and brings them back to the laboratory bench (and in some cases back to the bedside). This book fills a gap in the literature on developing epilepsy by bridging current clinical knowledge with basic and translational research in the developing brain relevant for developmental epilepsy. We use electrophysiological, molecular, and anatomical techniques to evaluate neuronal circuitry in normal and in epileptic brains. Huguenard, John, PhD. We are interested in the neuronal mechanisms that underlie synchronous oscillatory activity in the thalamus, cortex and the massively interconnected thalamocortical system.

  Recent experimental evidence on the clustering of glutamate and GABA transporters on astrocytic processes surrounding synaptic terminals pose the question of the functional relevance of the astrocytes in the regulation of neural activity. In this perspective, we introduce a new computational model that embeds recent findings on neuron–astrocyte coupling at the mesoscopic scale intra- and Cited by: 2. Conclusion: The findings elucidate the mechanisms by which downregulation of the expression and reduction of the activity of KCNQ2/3/5 channels in diabetic rat dorsal root ganglion neurons contribute to neuronal hyperexcitability, which results in hyperalgesia. These data provide intriguing evidence that activation of KCNQ2/3/5 channels might be. neuronal hyperexcitability by a novel neuron-glia mass model Aurélie Garnier, Alexandre Vidal, Habib Benali To cite this version: Aurélie Garnier, Alexandre Vidal, Habib Benali.

Benign familial neonatal seizures are an autosomal-dominant epilepsy presenting with seizures in the first or second week of life, most commonly starting on day of life 2 or 3, resolving within weeks to months.

Most seizures have stopped at 4 to 5 months of life. In this chapter, we aim to review the current trends in the molecular and cellular mechanisms in charge of neurological damage following mild TBI (mTBI) with a particular focus on neural hyperexcitability as well as discussing positive treatment findings that aim to mitigate the neuronal damage following : Nicola Maggio, Vardit Rubovitch, Barry J.

Hoffer, Bruce A. Citron, Nigel H. Greig, Chaim G. Pick. Self-propagating waves of cerebral neuronal firing, known as spreading depolarisations, are believed to be at the roots of migraine attacks. We propose that the start of spreading depolarisations corresponds to a critical transition that occurs when dynamic brain networks approach a tipping point.

We show that this hypothesis is consistent with current pathogenetic insights and observed dynamics. isolated spikes resulting from synchronous neuronal activations.
