Figure 5Left, superimposed representative traces of the normalized inward current evoked in a WT (black trace) and a KI corticalastrocyte (blue trace) by extracellular stimulation with a train of 10 pulses at 50 Hz in cortical slices. The inset shows in an expanded time scale the portion of the traces indicated by the dotted line. The slowly decaying current (τdecay = 2.00 s and 3.04 s for the WT and KI trace, respectively) is largely a [K+]e-dependent K+current (IK) whose decay kinetics provide a measure of the rate of K+ clearance by astrocytes (see text). Right, time constant of decay of IK elicited by trains of 10 pulses at 50 Hz in corticalastrocytes from P22-23 WT (n = 21; N=12) and KI mice (n = 20; N=8). IK τdecay is 22% higher in KI compared to WT astrocytes (unpaired t-test: P = 0.001).
