however, the presence of epileptiform activity alone does not diagnose epilepsy. Epileptiform patterns include spike and sharp wave discharges, either alone or accompanied by slow waves, occurring singly or in bursts lasting at most a few seconds.

10) Hemispherectomy may be indicated when an individual has a seizure disorder uncontrolled by medical intervention, a hemiparesis contralateral to the hemisphere with seizure activity, and the absence of epileptiform discharges ipsilateral ... There was no evidence of epileptiform activity on EEG throughout the 24 hours.

Most types of epileptiform activity with synaptic transmission have been shown to propagate from the CA3 to CA1 region in hippocampus. ... Understanding the propagation modes of epileptiform activity, and their causality is important to revealing the underlying mechanisms of epilepsy and developing new treatments.

With the low-Mg(2+)-model of epilepsy, this study investigated the effect of electrical LTD, chemical LTD, and depotentiation on the susceptibility of the entorhinal cortex to epileptiform activity. METHODS: The experiments were performed on isolated entorhinal cortex slices obtained from adult Wistar rats and mice.

Here we show that the increase occurs at an age before onset of cortical epileptiform activity and at a time when the frequency of mEPSCs in control layer V pyramidal neurons is stable.
