Fig. 12.

Trajectories of SATs formed by the DPM, CM, and CP lineage groups. The composition of this figure follows the same plan explained for Fig. 7, with sets of z-projections (A, D, E) illustrating segments of the SATs and fascicles at different antero-posterior levels, neuropil surface views showing location of SAT entrypoints ((B) and (C)) and neuropil cut-away diagram depicting SAT trajectories (G). Position of A, D, and E along the antero-posterior axis is indicated by white arrows. Panel B shows posterior view of both brain hemispheres. C presents enlargement of posterior view of right hemisphere. White lettering on right side of B and G annotates neuropil compartments; hatched circles and white lettering on left side of B indicates SAT entry portals; yellow lettering in G indicates fascicles (for alphabetical list of abbreviations, see Table 2). Scale bars: 25 μm ((A), (D)–(F)); 50 μm ((B) and (C)).
