Iterates for a weakly hyperbolic limit cycle of the conductance-based model. Sequences $K({\theta }_n,{\sigma }_n)$ computed using the 2-dimensional map (22) and the 1-dimensional map (23), respectively, for system (35). The strength of the stimulus is $ϵ=0.574604$, while the stimulation period is $T_s=0.026111\approx T_0/50$
