Astrocytes - Analysing Potassium Currents
Left: Comparison of K+ current voltage relationships for rat astrocytes on the Patchliner (closed circles, n = 19) and on a conventional setup (open squares, n = 10). Currents were measured as a response to a voltage step protocol.
Right: Normalized K+ current amplitudes in rat astrocytes. Internal solution was changed to the same solution (K+, open circles, n = 7) or to one where Cs+ was substitued for K+ (Cs+,closed circles, n = 7). Currents were measured as responses to voltage steps from −100 mV to +40 mV.
