Color: green = synaptic bodies
A. different stereo motion pictures of a reconstructed field of synaptic bodies inside a Sprague-Dawley rat pinealocyte with a section as background
The animations demonstrate the three-dimensional morphology of 7 synaptic bodies (sbs). They all are ribbons, some are strongly bent, one seems to have resulted from two
fused sbs. In order not to show the structures as closely as possible to their true shape no interpolations or smoothing algorithms were applied. Two sbs look somewhat
disrupted due to fact that they were nearly sagittally cut in the original sections. All sbs are more or less bent in at least one direction and only two are completely contained in
the investigated tissue volume. Also note the deep invagination of the cell membrane close to the field and several clathrin coated vesicles. The oriented stack of original images
from which the reconstructions were done is shown in C.

D. stereo animation in 3D "true colour", i.e. original grey tone as in the micrographs, from another reconstructed area
Three plate-like SBs close to the membranes of two adjacent cells one of which clearly shows the pentalamellar structure of SBs that is only visible when they are exactly seen from the direction of their long axis, i.e., if they are positioned exactly at right angle to the section plane.
