Figure 1 Sections of the Insect Brain Visualized with Various Markers Frontal sections of the same region of the Drosophila brain are shown. Yellow and white characters denote the names of the synapse-rich neuropils and fiber bundles, respectively. (A) Cytoplasmic dsRed (red), synaptic-vesicles-targeted n-syb-GFP (green), and GABA-receptor-targeted Rdl-HA (blue) expressed by the pan-neuronal elav-GAL4 expression driver, with outlines of neuropil boundaries superimposed. (B) Silver stain (paraffin section) to visualize neural fibers. (C) Anti-Bruchpilot nc82 antibody to visualize the density of synapses. (D) Cytoplasmic GFP expressed by the pan-glial repo-GAL4 expression driver. (E) Anti-β-tublin antibody to visualize fibrous structures of neurons and glia. (F) Anti-Discs-large antibody to label membranes of neurons. (E) and (F) are superimposed with the repo-GAL4-driven GFP signal (orange) to visualize glial processes. Bar indicates 50 μm.

(B) Hierarchical list of the defined synaptic neuropils. See Table 1 for abbreviations. (C) Resolution of problematic nomenclature between species for the olfactory tract. (D) Resolution of problematic nomenclature pertaining to brain ganglia. See text for explanation of abbreviations. (E and F) Resolving confusing terms for the axis systems.
