Table B.2: Non-uniform channel model and kinetics, Lv ɑ. and ⅛ use Hodgkin-Huxley
type kinetics, while
Ia uses Connor-Stevens type kinetics and a spatial distribution of
conductance based on Hoffman’s work. For G(rr),
x is measured in pm from the soma.
Note that the
Ia channel kinetics do not have a and β functions explicitly defined (Connor
and Stevens, 1971) (Hoffman et al., 1997).
