The membrane potential starts to integrate incoming currents again until it reaches the lower threshold \(V_{(th-low)}\) of -0.2 V. As the membrane potential gradually increases, the Schmitt trigger circuit detects the crossing of \(V_{(th-low)}\) of -0.2 V and generates another positive spike indicating another action potential. As the membrane potential crosses the upper threshold, this process repeats generating action potentials at regular intervals as shown in Figs. 7.1 and 7.2.

摘要

The membrane potential starts to integrate incoming currents again until it reaches the lower threshold \(V_{(th-low)}\) of -0.2 V. As the membrane potential gradually increases, the Schmitt trigger circuit detects the crossing of \(V_{(th-low)}\) of -0.2 V and generates another positive spike indicating another action potential. As the membrane potential crosses the upper threshold, this process repeats generating action potentials at regular intervals as shown in Figs. 7.1 and 7.2.
