Figure 4. — Voltage dependence of total variance from the same patch as Figs. 2 and 3. Symbols have the same meaning. The midpoints of the P _open-voltage relationships determined as described in Fig. 7, are indicated by symbols near the X axis. The open symbols show the band-limited Lorentzian component of the σ² in this experiment, , obtained by fitting power spectra with Lorentzian plus 1/f components (as described in Fig. 10). There is divergence only at large depolarizations at pH_i 5.0, where the 1/f component became significant. ES-2596.
