Length constant λ
Figure 5.7 : These plots show the key parameters for describing the steady-state voltage dis-
tribution in a ID and 2D cable. The results are for a point source, as 7 = Rc∣Rm is varied.
(A) Normalized length constant D∕λ plotted vs 7 = Rc]Rm. (B) Input impedance Rin rela-
tive to membrane resistance Rm as a function of 7 = Rc]Rm. (C) Input impedance Rin∣Rm
vs normalized length constant D∕λ for the ID and 2D case.
