NEURON mod files for the Ih current from the paper:
McCormick DA, Pape HC.
Properties of a hyperpolarization-activated cation current
and its role in rhythmic oscillation in thalamic relay neurones.
J. Physiol. 1990 431:291-318.
Running the kinetics.hoc simulation file will show
the activation steady-state, the time constant, a simple simulation
using a somatic current injection, and a family of curves
generated modeling the same protocol used in the experiments.
Since the experimental values were not explicitly given in the paper,
the voltage dependence of the time constant for activation and
de-activation (Fig.3A) has been approximated with an arbitrary function
using a temperature of 36C, as in the experiments.
Under unix systems:
to compile the mod files use the command
and run the simulation hoc file with the command
Under Windows using NEURON 5.2:
to compile the mod files use the "mknrndll" command.
A double click on the simulation file
will open the simulation window.
