Excitatory effects of parvalbumin-expressing interneurons maintain hippocampal epileptiform activity via synchronous afterdischarges
Epileptic seizures are characterized by periods of hypersynchronous, hyperexcitability
within brain networks. Most seizures involve two stages: an initial tonic phase, followed by a …

Excitatory GABAergic signalling is associated with benzodiazepine resistance in status epilepticus
Status epilepticus is defined as a state of unrelenting seizure activity. Generalized convulsive
status epilepticus is associated with a rapidly rising mortality rate, and thus constitutes a …
