Video Supplements

Files in this Data Supplement:

• Movie 1 - Mitochondrial movement in motor axons. Single axonal mitochondria are visualized, and both anterograde and retrograde movements can be observed. Notice that the mitochondrial flow rates differ in different synaptic branches.
• Movie 2 - The delivery of mitochondria during tetanic stimulation. The actual time of recording was 10 min, but this movie consists of 60 frames with a 10-s interval between each frame. Frames of the selected area had a 1.1-s scanning time per section, and were projected from a stack of 10 optical sections (0.5 µm/section). During tetanic stimulation, mitochondrial movement can be both anterograde and retrograde, and both are shown. Notice the different destinations of anterograde mitochondria when they reach the synaptic terminal.
