The role of focal and extrafocal structures in the triggering of epileptic spikes: an experimental study.
Experiments carried out in cats with a neocortical cobalt induced epileptic focus demonstrated that focal averaged spikes, obtained by a personal computer technique, can alternatively lead the caudate ones or be led by them. Defined morphological alterations of the spikes characterize the two situations.
