Average brain representations of Gal4 enhancer trap lines. Maximum projections through 80 Gal4 enhancer trap lines that were imaged, registered and averaged for this study. Gal4 expression was visualized using the UAS:Kaede transgenic line (magenta). Each panel is the average of at least three brains. For contrast, each panel also shows ubiquitous ²actin:Switch expression (gray) and pan-neuronal HuC:Cer expression (blue, after application of brain mask). Scale bar (bottom right panel) 100 µm. |
