4AP-Induced epileptiform discharges in sagittal PC slices. (A) Recording obtained from layers I and II of the anterior PC showing the generation of an ictal discharge followed by the occurrence of interictal events. The onset of ictal activity is preceded by a fast field event (expanded in a) resembling an interictal discharge (d). The ictal event is characterized by the initial manifestation of tonic activity (b), which gradually slows down and is replaced by clonic discharges made of population bursts (c). (B) Frequency distributions of time delays of epileptiform events. The anterior PC appears to drive the generation of ictal activity, whereas interictal events are generated equally by both the anterior and the posterior subregions.
