Fig. 22. Characteristics of lineage 20 (NB 5-4). (A) Ventral view of the projection of a MARCM clone of lineage 20. (B-D) Thick section projections showing the relationship of the neurite bundles from lineage 20 to features of the Neurotactin scaffold (red) in intermediate (B) and ventral (C,D) neuropil. Bundle 20 converges with bundles 22 and 21, and projects along the lateral edge of the ventrolateral neuropil. It also contains 2 axons that project to the periphery. Numbers identify neurite bundles from other lineages. Diagrams as in Fig. 2. Commissure abbreviations as in Fig. 1; VA, ventral arch.
