K-a channel, from migliore et al. (1999), model no. 2796, based on hoffman et al. (1997) ca1 data. Activation time constant, forward and backward rates parameterized to allow for differences between proximal and distal ka. Ability to shift (in)activation curves and change time constants added via parameters. Minimum inactivation time constant added. Note that it is unclear if this file is more similar to the distal or proximal version from model no. 2796, but the proximal version is cited as the ancestor. Modeling study, with animal and neuron model from the morphology used here.
