Movie 3.

An animated 3-d reconstruction of the optic nerve arborization along the lateral neuropil of Acanthopleura granulata. This video is a 3-d reconstruction of the left section of Fig. 5C, which is a composite maximum projection image. The large white nerve in the video is the optic nerve labeled with a white arrow in Fig. 5C, and magenta neurites in the video are the traversing neurites of the optic nerve labeled with a magenta arrow in Fig 5C. The white fasciculated optic nerve splits into two separate neurite bundles which travel to separate tracts of the neuropil. The white- and magenta-labeled optic nerves are seen to travel in close proximity to one another and both have periodic varicosities that are likely en passant synapses.
