Figure 2.

When the voltage range of oscillation was increased or decreased, the preferred frequency (Freq.) shifted in the same direction. A1, The impedance profiles of the PD neuron measured in voltage clamp using ZAP functions with a fixed lower bound (−60 mV) and various upper bounds (inset, blue, −34 mV; red, −30 mV; green, −26 mV). A2, The preferred frequency increases when the upper bound is increased (N = 15; p < 0.001). B1, The impedance profiles with a fixed upper bound (−30 mV) and various lower bounds (inset, blue, −70 mV; red, −60 mV; green, −50 mV). B2, The preferred frequency also increases when the lower bound is increased (N = 12; p < 0.05). C1, The impedance profiles with a shifting voltage range, as indicated in the inset and legend. C2, The preferred frequency increased with the voltage range of oscillation (N = 9; p < 0.001). Yellow data points in A2, B2, and C2 show values in individual experiments. Error bars show SD values.
