<p>Somatic voltage responses in IN1, resting at -63 mV (<b>A1</b>), and IN2, resting at -69 mV (<b>A2</b>) to 7 current pulses of different intensity. When IN1 was held at -57 mV, a strong hyperpolarizing current injection was followed by a rebound burst (<b>B1</b>). When IN2 was held at -58 mV, a strong hyperpolarizing current injection did not cause a burst (<b>B2</b>). Current injections were applied as 900 ms step pulses to the soma, with intensities as indicated below the traces. Two repetitions were made of each CC-experiment, whereof one is shown. The voltage scale bar applies to all panels (A-B). <i>I<sub>h</sub></i> was measured at different potentials from -130 mV with 5 mV steps, in three different neurons. Recordings are shown for one neuron (<b>C</b>).</p
