Numerical solutions for steady-state vesicle concentration as a function of axonal distance for different values of \(\phi=k_{-}/\gamma _{c}\) and \(J_{0} = 1.5\). (Adapted from [20].) For comparison, the corresponding concentration profile when \(J_{0}=0\) (which is insensitive to Ï•) is shown by the thick line (red line in color online). We have also set \(\gamma= 10^{-2}~\mbox{s}^{-1} \), \(\widehat{J}=1.5\), \(k_{+} = 0.5~\mbox{s}^{-1}\), \(k_{-}=1.0~\mu\mbox{ms}^{-1}\), \(v= \widehat{v} = 1~\mu\mbox{ms}^{-1}\) and \(D =\widehat {D}= 0.1~\mu\mbox{ms}^{-2}\)
