Figure 4.
Ionic currents during burst and interburst activity at 8 mM [G] (A) and 16 mM [G] (B). Top panels show Vm and bottom panels show individual ionic currents, with the different colors as indicated on the right. The amplitudes of individual currents were measured at the plateau potential (the most negative potential between successive action potentials) during the burst period. Note that different time scales are used in A and B. The zero current level is indicated by dotted lines. Gray bars indicate the interburst period, where the VL analysis was applied in Fig. 5.
