Hh channel including both a soidum and delayed rectifier channel and accounts for sodium conductance attenuation, modified by b mel, t brannon and y poirazi separately, updated by m markaki 2003. From markaki et al. (2005), model no. 119266. This is a modeling study, the animal model info here is from the morphology used (pyapali et al. 1998). Ancestor model and channel kinetics have similar animal and neuron model (mostly from poirazi et al. 2003).
