Example cell-type-specific lines.

(A) Split-GAL4 line SS52577 is expressed in P-FNv neurons arborizing in the protocerebral bridge, fan-shaped body, and nodulus (Wolff and Rubin, 2018). (B) Split-GAL4 line MB043C is expressed primarily in PAM-α1 dopaminergic neurons that mediate reinforcement signals of nutritional value to induce stable olfactory memory for driving wind-directed locomotion and higher-order learning (Aso et al., 2014; Ichinose et al., 2015; Aso and Rubin, 2016; Aso et al., 2023; Yamada et al., 2023). (C) Split-GAL4 line SS40265 is expressed in members of the 8B(t1) cluster of cholinergic neurons that connect the lower tectulum neuropil of the prothorax with the gnathal neuropil and the ventral most border of the vest neuropil of the brain ventral complex. (D) Split-GAL4 line SS60203 is expressed in ascending neurons likely innervating the wing neuropil. (E) Split-GAL4 line SS47938 is expressed in LBL40, mediating backwards walking (Feng et al., 2020; same sample used in Figure 5b, CC-BY license). (F) Split-GAL4 line SS36564 is expressed in female-specific aIPg neurons (F1) and not observed in males (F2; Schretter et al., 2020). (G) MCFO of split-GAL4 line SS72207 with specific expression in DNg34, a cell type described in Namiki et al., 2018. Scale bars, 50 µm. See Figure 1—source data 1 for more line information and Supplementary file 1 for images of all cell-type-specific lines.

Examples of line quality levels.

The 3060 cell-type lines were scored for expression. (A) Quality level 1 (1767 lines): Split-GAL4 line OL0015B (Wu et al., 2016) is specifically and strongly expressed in a single cell type. Occasional weak expression may be seen in other cells. (B) Quality level 2 (1232 lines): Split-GAL4 line SS59643 (Wolff et al., 2024) has expression in two cell types. Occasional weak expression may be seen in other cells. (C) Quality level 3 (26 lines): Split-GAL4 line SS59643 (Wolff et al., 2024) has expression in three or more cell types. (D) Quality level 4 (34 lines): Split-GAL4 line SS61022 has specific expression but weak or variable labeling efficiency. See Figure 2—figure supplement 1 for examples of variable expression. (E) Quality level 5: IS36417 is an Initial Split combination not selected for stabilization. Groups of neurons are visible, but the cell type of interest was not labeled with sufficient specificity for further work. Such lines were only included in the raw image collection. Scale bars, 50 µm.

Spatial distribution of cell-type lines.

(A–D) Images of one male and one female sample from 3029 cell-type rescreening lines were aligned to JRC2018 Unisex (Bogovic et al., 2020), segmented from background (see Methods), binarized, overlaid, and maximum intensity projected, such that brightness indicates the number of lines with expression. All images were scaled uniformly to a maximum brightness equal to 206 lines on Fiji’s ‘royal’ LUT (scale inset in D). This saturated a small portion of the male antennal mechanosensory and motor center (AMMC) that reached a peak value of 260 lines per voxel, for the purpose of better visualizing the rest of the central nervous system (CNS). (A) Female CNS. (B) Male CNS. (C) Female image stack minus male, then maximum intensity projected. (D) Male image stack minus female, then maximum intensity projected. (E, F) Split-GAL4 line SS56987 (Schretter et al., 2020) is sex-specifically expressed in pC1d neurons that largely lie within the region of the female central brain highlighted in (C). Male and female images have different brightness scales. (G, H) Split-GAL4 line SS35230 (Shuai et al., 2024) is sex-specifically expressed in abdominal ganglion neurons that largely lie within the region of the female ventral nerve cord (VNC) highlighted in (C). Male and female images have different brightness scales. All scale bars, 50 µm.

Spreadsheet for coverage analysis.

3D histograms were calculated for the brain and ventral nerve cord (VNC) heat maps in males and females. Percent coverage over a specified threshold was calculated. The brain and VNC were further subdivided into regions with individual histograms and weighted average coverage levels.

Summary of FlyLight adult fly line and image releases.

Includes descriptions of Jenett et al., 2012; Dionne et al., 2018; Tirian and Dickson, 2017; publications in Table 1; and stock distribution by Bloomington Drosophila Stock Center and Janelia Fly Facility. Section with italic text is specific to publications from Table 1 and this publication. Image counts are unique between categories, whereas line counts overlap extensively between categories. ‘Image tiles’ are considered as unique 3D regions, with each MCFO tile captured using two LSM image stacks. Stock shipments count each shipment of each stock separately. Raw and processed images are available at https://www.janelia.org/gal4-gen1, https://gen1mcfo.janelia.org, https://splitgal4.janelia.org, and many can be searched based on anatomy at https://neuronbridge.janelia.org.

Supplementary file 1

Images of cell-type-specific adult split-GAL4 lines.

Images are averaged color depth MIPs from rescreened and raw collection SS screen and polarity neuron channel images (Otsuna et al., 2018). Images were inverted, overlayed on a 2D outline of JRC2018, and composited. Depth color scale for inverted color depth MIPs is on first page, running from yellow on the anterior brain (or ventral VNC) to blue on the posterior brain (or dorsal VNC).

Guide to FlyLight data.

A guide to interpreting the images at https://gen1mcfo.janelia.org and https://splitgal4.janelia.org further describes data organization, labeling, and imaging methods. Images at https://www.janelia.org/gal4-gen1 are processed as described in Jenett et al., 2012.
