Figure 5. The dynamics of somatic vesicles pre-and post-depolarization.

Figure 5

Three-photon excitation microscopy shows dynamics of somatic serotonergic vesicles (or unresolved vesicular clusters) in the cell body and in the processes before and after KCl-induced depolarization. (A) Individual tracks of a few serotonin fluorescent spots before (top) and after (bottom) depolarization. In (B–D), red and blue denote measurements performed before and after depolarization, respectively. (B) Average displacement from the track origin compared with time. (C) Velocity distribution obtained from the tracks. (D) MSD compared with time (error bars correspond to S.E.M.).
