COMMENT ----------------------------------------------------------------------------- Leak potassium current ---------------------- This mechanism was written to be used as a potassium channel that is open or closed by neuromodulators. WARNING: this current is NOT inserted as a standard current, but as a point process (same way as a synapse or current injection). Procedure for insertion: objectvar kl kl = new kleak() access kl.loc(0.5) kl.gmax = ... A.
