This model was converted from XPP ode format to SBML using sbmlutils-0.1.5a6.
# Simplified 2D HH model
# formatted for use with XPPAUT
# Parameters as in the model of Figure 8, Lundstrom et al, J Comp Neurosci
# Note: the z variable introduces stimulus noise and must be removed for bifurcation analysis
