Parameters in nanosiemans per square micrometer denote maximal conductances of corresponding currents in the STN current balance equation. Parameters in millivolts represent reversal potentials for these currents. Parameters in milliseconds are time constants relating to the time evolution of the gating variables in the Hodgkin–Huxley representations of these currents, whereas other parameters are associated constants.
