Borg-graham like k-m channel, included in axon. Based on model for ca3 pyramidal neuron in migliore et al. (1995), model no. 3263, slightly changed to account for the firing accommodation shown by ca1 neurons (lines 19-21), and q10 equation (line 68). Modeling study, with kinetics partially taken from migliore et al. (1995), halliwell and adams (1982), and others, all based on rodent studies.
