Computer models predict differential dendritic vulnerability with ischemia and spreading depression

Ischemia, whether abrupt or chronic, limits ATP production and disrupts ATP-dependent homeostatic mechanisms, leading to alterations in both intracellular and extracellular ion concentrations. Inadequate neuronal ATP triggers K+ release and increased extracellular K+ depolarizes neurons, leading to additional K+ releas...
