[SD has been observed in a variety of in vitro and in vivo epilepsy models in different animal species. Reduction of extracellular Mg2+ concentrations, activation of NMDA receptors, blocking of K+ channels,] e.g., by 4-aminopyridine, increased extracellular K+, blocking of Na+–K+ ATPase, e.g., by ouabain, blocking of Ca2+ channels, e.g., by NiCl2, blocking of GABA receptors, e.g., by picrotoxin, are the common pathways for eliciting epileptiform burst discharges and SD in experimental models. By all aforementioned mechanisms SD appears spontaneously between epileptiform ictal events. SD can be elicited in susceptible area by a single discharge of an epileptic focus (spike triggered SD). Epileptiform field potentials usually suppress during SD occurrence and reappear in few minutes. CSD penetration into the epileptic foci was established in different model of epilepsy. However, it should be noted that SD does not enter electrically or pharmacologically elicited foci of epileptic activity with high rates of interictal discharges which resulted in anomalous SD propagation. This abnormal SD conduction may account for periodic changes of ictal and interictal activity found in some types of focal epilepsy.
