Potassium inward rectifier after geukes, foppen and siegenbeek, with instantaneous kinetics. Paper says it is modeled after fig 1 of siegenbeek van heukelom (1994). This model is based on previous papers by kager et al. (2002, 2007), with kinetics taken mostly from traub et al. (1994/1993). No apparent modeldb ancestors. Model is based on previous paper, which use mode files that cite traub et al. (1994). Since all of the models are generic, we cite traub et al. (1994) for the animal model here, which is a model of rodent hippocampus.
