Spontaneous changes in leak conductance and its effects. A, B A recording with a low Rm (A) was followed by a recording with a relatively high Rm (B); C, D Spikes from the low- (C) and high-resistance (D) recordings; color coding is the same as in A and B, respectively. E Dependencies of membrane time constants and capacitances on the response voltage immediately after the spike. F Dependencies of membrane resistances on the response voltage immediately after the spike; A–F, data from the same cell. G Time courses of changes in Rm (top) and resting potential Vrest (bottom) during one experiment. H–K Correlations between Rm and Vrest during similarly prolonged recordings in 4 cells
