Figure 7. — Lithium currents and di-8-ANEPPS signals from detubulated fibers. (A) I_Li records elicited by 25-ms depolarizations to −70-, −50-, −45-, −40-, −35-, 0-, 20-, 40-, 60-, and 80-mV pulses (black, blue, red, green, orange, brown, cyan, magenta, gray, and purple traces, respectively). Only the first 5 ms are shown. No currents were seen at the pulse off (not depicted). Fiber parameters: radius, 23 µm; length, 329 µm; capacitance, 2 µF/cm². (B) Voltage dependence of peak I_Li for the fiber in A. (C) Voltage dependence of the average peak I_Li (n = 4). Symbols and bars are the average and SEM. Fiber parameters: radius, 25.7 ± 1.1 µm; length, 421.2 ± 40.3 µm; capacitance, 2.5 ± 0.28 µF/cm². (D) Di-8-ANEPPS transients elicited by 20-ms depolarizing pulses of 20, 60, 100, and 140 mV. Spot illumination was 50 µm. Data are from the same fiber as in A.
