  • The development of concepts describing potassium clearance mechanisms in the mammalian central nervous system in the last 35 years is reviewed. The pattern of excess potassium in the extracellular space is discussed as are the implications of these potassium levels for neuronal excitability. There is a systematic description of the available evidence for astrocytic involvement in situ. The three possible astrocytic potassium clearance mechanisms are introduced: spatial buffer mechanism; carrier… CONTINUE READING
