Figure 5From: Dual patch voltage clamp study of low membrane resistance astrocytes in situSimultaneous acquisition of V M , I M , and R M in dual patch recording. (a, b) Bath application of 1 mM GABA induced VM depolarization, and inward currents were measured simultaneously by the two electrodes. The measurements are identical in astrocytes from P13 (a) and P21 (c) mice. However, only in the RM measurement of P21 astrocytes, three ionic events are temporally distinct (c). (b) Quantification of a GABA-induced RM decrease in P9-P13 mice. (d) Quantification of a GABA-induced RM change in P21 mice. The control, first, and second events correspond to the black, red and blue filled circles shown in the bottom panel of c, respectively.Back to article page
