Values are channel conductance densities for fast sodium current (NaF), fast Kv3 family (fKdr) and a slow Kv2 family delayed rectifier current (sKdr), tonic nonspecific cation current (TNC), calcium-gated voltage-independent potassium current (SK), low-voltage-activated T-type calcium current (CaT), slowly inactivating persistent sodium current (NaP), and hyperpolarization-activated current (IH) and permeability for high-voltage-activated calcium current (CaHVA) for the different compartment types. Axon refers to the conductance densities and CaHVA permeability in the axon hillock and initial segment.
