Comments:
Hyperpolarization-activated current (h-current). Two distinct activation gates, from destexhe, babloyantz & sejnowski (1993). Ancestry is unclear, no apparent ancestors. This is from a tutorial, not much is explained about the model. The animal model here is from huguenard and mccormick (1992), and most kinetics are from there as well.
Temperature:
Model has temperature dependence, default at 35.5 deg C, and q10 set to 3.
