Figure 3. Cooling from 35 to 25°C.
Normal nerves (left) and 39-month-regenerated nerves (right) were investigated at 35°C (grey areas), 30°C (lines) and to 25°C (open symbols). Error bars and grey areas indicate ± s.e.m. Graphs illustrate 40% depolarizing threshold electrotonus (A and B), 40% hyperpolarizing threshold electrotonus (C and D), current–threshold relationship (E and F), recovery cycle for 1 ms pulses (G and H) and chronaxie (I and J).
