Neuronal network synchronization and limbic seizures

P>Seizure discharges involving hippocampus and parahippocampal structures are the hallmark of temporal lobe epilepsy (TLE). Herein we discuss neuronal synchronization in limbic networks from control and epileptic brains under conditions that are inductive for the generation of seizure-like discharges. In particular, we address the paradoxic role played by inhibitory mechanisms in supporting epileptiform hypersynchrony.
