Astrocytic gap junction blockade markedly increases extracellular potassium without causing seizures in the mouse neocortex
Extracellular potassium concentration, [K+]o, is a major determinant of neuronal excitability. In the healthy brain, [K+]o levels are tightly controlled. During seizures, [K+]o increases up to 15 mM and is thought to cause seizures due to its depolarizing effect. Although astrocytes have been sugges...
