## Abstract Application of the GABA~A~ receptor agonist muscimol to astrocytes in situ or in vitro results in a receptorβmediated Cl^β^ current with a concomitant block of outward K^+^ currents. The effect on K^+^ current is largely selective for the inactivating Aβtype current. Parallel experiment
Elevation of the extracellular potassium concentration above its "resting" level of 5.4 mM stimulated uptake of 45Ca2+ in primary cultures of astrocytes. This effect was only observed when cells were exposed to excess potassium shortly after their exposure to 45Ca2+ and was potently inhibited (IC5,,
