COLOR CODE unc30-1 October 1988
Codes taken from MRC Neuron Charts September 16, 2008; DHH
This young adult has been extensively reconstructed in the anterior ventral cord and dorsal cord. The most synaptically-active ventral cord axons were reconstructed using a red and blue color code, and a separate blue color code for the dorsal cord. Many chemical synapses are visible on the prints. Original reconstructions were done by hand by Marilyn Anness and Eileen Southgate, and several additional unc30 animals were reconstructed in 1984 (also in our collection). A few motoneuron cell bodies seem to be slightly mispositioned along the A/P axis (DD2 is about 3 cell body positions too posterior, as was also noted in one of the adults from 1984). The most striking defects are the incorrect NMJs formed by VDs and DDs in this animal. VDs retain NMJs to dorsal muscles (as in normal L1s) and have few or none to ventral muscles (where there ought to many). DDs have too few NMJs to dorsal muscles (should have many more), and apparently none to ventral muscles (which is normal).
This dataset stems from original unpublished work by John White and colleagues at the MRC.
