• Comments: C-amp modulated cation channel. Kinetic model of hcn2 channel gating from wang et al (2002), model no. 19176, with various modifications. J held's adaptation to suit hcn2. Animal model is from experiments in paper. Hcn channel kinetics come from previous model of thalamocortical relay cells (wang et al. 2002).
