Absence-like seizures in adult rats following pilocarpine-induced status epilepticus early in life. B.L.C. Ferreira, A.C. Valle, E.A. Cavalheiro and C. Timo-Iaria. Brazilian Journal of Medical and Biological Research, 36 (12): 1685, 2003.

Figure 3. Tracings of an absence seizure recorded in a computer, demonstrating a perfect building up of a seizure spike-wave, which oscillates at 8 Hz. Notice the concomitancy of the cortical and CA1 hippocampal potentials. In the latter, the slow waves are quite clear but the spikes are sometimes deformed, although clearly present. In CA3 and in the thalamic ventrolateral nucleus the slow potentials of the spike-wave complexes appear, although also deformed. Abscissa: time in 0.5-s intervals after the beginning of the acquisition period. For abbreviations, see legend to Figure 1.
