Fig. 18
Three-state model of the bidirectional transport of a single motor-cargo complex. The particle switches between an anterograde state (\(n=+\)) of speed \(v_{+}\), a stationary or slowly diffusing state (\(n=0\)), and a retrograde state (\(n=-\)) of speed \(v_{-}\). The motor-complex can only deliver a vesicle to a presynaptic target in the state \(n=0\)
