[HTML][HTML] Chloride ion dysregulation in epileptogenic neuronal networks
SA Weiss - Neurobiology of Disease, 2023 - Elsevier
GABA is the major inhibitory neurotransmitter in the mature CNS. When GABA A receptors
are activated the membrane potential is driven towards hyperpolarization due to chloride …

A model for focal seizure onset, propagation, evolution, and progression
We developed a neural network model that can account for major elements common to
human focal seizures. These include the tonic-clonic transition, slow advance of clinical …

Network properties revealed during multi-scale calcium imaging of seizure activity in zebrafish
J Liu, SC Baraban - eneuro, 2019 - eneuro.org
Seizures are characterized by hypersynchronization of neuronal networks. Understanding
these networks could provide a critical window for therapeutic control of recurrent seizure …

Focal cortical seizures start as standing waves and propagate respecting homotopic connectivity
Focal epilepsy involves excessive cortical activity that propagates both locally and distally.
Does this propagation follow the same routes as normal cortical activity? We …
