Astrocytic Ion Dynamics: Implications for Potassium Buffering and Liquid Flow

no code implementations • 9 Jun 2016 • Geir Halnes, Klas H. Pettersen, Leiv Øyehaug, Marie E. Rognes, Gaute T. Einevoll

We review modeling of astrocyte ion dynamics with a specific focus on the implications of so-called spatial potassium buffering, where excess potassium in the extracellular space (ECS) is transported away to prevent pathological neural spiking.
