Figure 4
Nonuniform phase dynamics in the Hodgkin-Huxley neuron. The angular velocity \(\Omega (\varphi )\) exhibits a highly non-trivial dependence on the U(1) phase. In the regime of current stimuli from 6.3 \(\mu\)A/cm\(^2\) (red) to 46.3 \(\mu\)A/cm\(^2\) (blue), one finds the overall shape remains more or less the same. However, because the firing rate is dictated by the bottleneck regime, a slight increase of the angular velocity here will boost up the firing rate significantly.
