EM-based reconstruction of JONs.
(A) JON projections from the second antennal segment (a2) into the AMMC brain region (brain neuropile shown in gray). Anterior, dorsal, and lateral views of reconstructed JONs are shown. (B–G) Reconstructed JONs are shown from dorsal (top) and medial (bottom) views. (H–M) Dorsal (top) and medial (bottom) views of the JON pre- and post-synaptic sites are shown (colored dots) with a gray mesh that outlines the entire reconstructed JON population. See Figure 1—figure supplement 2 for pre- versus post-synaptic site distributions. All reconstructed JONs are shown in (B–G), but only fully reconstructed JONs are shown in (H–M) (JO-A and -B synapses not shown). JO-A and -B neurons were previously reconstructed by Kim et al., 2020. Colors in (A, B, and H) correspond to the zones to which the different JONs project, including zones A (dark gray), B (light gray), C (orange), D (red), E (green), F (blue), and mz (brown). Panels (C–G) and (I–M) show JONs that project specifically to zones C (C,I), D (D,J), E (E,K), F (F,L), or multiple zones (mz) (G,M). Color shades in (C–G) and (I–M) indicate different JON types that project to that zone. Zone subareas are indicated with labeled arrows. See Video 1 for 3D overview.

Correspondence between manual annotation and NBLAST clustering in the categorization of JONs.
(A) Dendrogram of hierarchically clustered scores from an NBLAST query of 147 reconstructed JONs. Oval colors indicate the manual assignment of each JON as projecting to a specific zone. Colors of specific neuron names indicate the manually annotated neuron types (e.g. JO-FVA in cyan, JO-FDA in dark blue). Branch numbers indicate JON groups that are shown in (B) resulting from a cut height of 1.4 (dotted line). (B) NBLAST-clustered JON groups (15 groups at h = 1.4). Neuron colors indicate manually annotated neuron types and correspond to the neuron type names in (A). The first panel shows how the JONs were pruned for NBLAST analysis to include only synapse-bearing parts of the neurons (JON parts used for NBLAST analysis shown in black, see Materials and methods for details) with pre- and post-synaptic sites in magenta and green respectively.

(A–D) Shown are maximum intensity projections of brains (anterior view) in which driver lines JO-C/E-1 (A), JO-C/E-2 (B), JO-F-1 (C), and JO-F-2 (D) drive expression of green fluorescent protein (mCD8::GFP). Brains were immunostained for GFP (green) and Bruchpilot (magenta). The arrow shown in (D) indicates a neuron that is not a JON. Scale bar, 100 μm. Figure 3—figure supplement 1 shows the ventral nerve cord expression pattern for each line. (E, F) Dorsal view of EM-reconstructed JON types (left panels) that are predicted to be in the expression patterns of the confocal light-microscopy (LM) images of driver-labeled neurons (middle and right panels). Driver line expression patterns of JO-C/E-1 (middle) and −2 (right) shown in (E) and JO-F-1 (middle) and −2 (right) shown in (F). Subareas are indicated with arrows. Note that in (F) the subareas FDL and FDA are not labeled because they are not visible in the dorsal view. Scale bar, 20 μm. (G) Table of JON types that are predicted to be in each driver expression pattern. The shading of each box indicates whether the predictions are supported by EM reconstructions alone (gray), or by EM and MCFO data (black). MCFO data is shown in Figure 3—figure supplement 2. (H, I) Computationally aligned expression patterns of JO-C/E-1 (green) and JO-F-1 (magenta) from anterior (H) and dorsal (I) views (left panels) in comparison with the EM-reconstructed JONs (right panels). Scale bar, 50 μm.

Stochastic labeling of individual JONs in the JO-F-1 and JO-F-2 expression patterns.
(A–F) Anterior view of different MCFO-labeled JON types in the expression patterns of JO-F-1 (top) and JO-F-2 (middle). Shown are maximum intensity projections of each JON expressing a tagged protein that is stained using a tag-specific antibody (see Materials and methods for information about the tagged protein and antibodies used). Top right corner of each panel indicates the number of JONs that were labeled for each type versus the total MCFO-labeled JONs that we obtained (white neurons are the type indicated). Note that the number of individual labeled JONs does not add up to the total number of MCFO-labeled JONs (27 out of 28 for JO-F-1 and 39 out of 42 for JO-F-2). The additional neurons were not included in the analysis because they had ambiguous morphology that could not be definitively linked to a particular JON type. Bottom panels show EM-reconstructed examples of each neuron type (neuron names are indicated in the top right corner). The JON types are JO-FDA (A), -FDP (B), -FDL (C), -FVL (D), -FVA (E), and -EVP (F). Scale bar, 20 μm.

The JO regions are color coded, including anterior-dorsal (A-D, mustard), posterior-dorsal (P-D, black), anterior-ventral (A-V, magenta), and posterior-ventral (P-V, gray). (C’–F’) Manually labeled JON cell bodies (dots) that expressed GFP in a confocal z-stack of each driver line. This highlights GFP-labeled JONs in the posterior JO that are difficult to view in the maximum projections shown in (C–F). The colors indicate the JO region where the cell body is located. Shown are JO-C/E-1 (C,C’), JO-C/E-2 (D,D’), JO-F-1 (E,E’), and JO-F-2 (F,F’).

Testing the responses of JO-C/E and JO-F neurons to stimulations of the antennae.
(A) Schematic lateral view of a fly antenna. An electrostatically charged electrode pushes or pulls the antenna via the arista towards or away from the head, respectively, or induces a 200 Hz sinusoid. (B–E) Calcium response of JONs to stimulations of the antennae. Flies were attached to an imaging plate, dorsal side up. The proboscis was removed to access the ventral brain for imaging GCaMP6f fluorescence changes (ΔF/F) in the JON afferents. Stimulations of the antennae were delivered for 4 s as indicated above the traces. 10 or 12 flies were tested for each driver line (N = number of flies tested). For each fly, four trials were run for each stimulus and then averaged. Each row shows the mean trace of all flies tested (black lines) from a different driver line expressing GCaMP6f, including JO-C/E-1 (B), JO-C/E-2 (C), JO-F-1 (D), JO-F-2 (E). The gray envelopes indicate the standard error of the mean. See Figure 5—figure supplement 1 and Figure 5—figure supplement 2 for statistical analysis.

Each trace represents the mean of four trials for each fly. The stimulus duration was 4 s and is indicated with blue boxes. 10 or 12 flies were tested for each driver line (N = number of flies tested). The mean traces of all the tested flies are shown in Figure 5B,C. (B,D) Plots of the measured fluorescence before and during each stimulus (NoStim and Stim, respectively) for the mean value of four trials for each fly (dots), and the median value of all flies (bars). The Wilcoxon signed-rank test was used for each condition (asterisks indicate *p<0.05, **p<0.001).

Responses of the JO-F neurons to mechanical stimuli: individual traces and statistical analysis.
(A–D) GCaMP6f was expressed in either JO-F-1 (A,B) or JO-F-2 (C,D). (A,C) Shown are the GCaMP6f fluorescence traces of individual flies while different mechanosensory stimulations were delivered. Each trace represents the mean of four trials for each fly. The stimulus duration was 4 s and is indicated with blue boxes. 10 flies were tested for each driver line (N = number of flies tested). The mean traces of all the tested flies are shown in Figure 5D,E. (B,D) Plots of the measured fluorescence before and during each stimulus (NoStim and Stim, respectively) for the mean value of four trials for each fly (dots), and the median value of all flies (bars). The Wilcoxon signed-rank test was used for each condition (asterisks indicate *p<0.05).

Optogenetic activation of JO-C/E or JO-F neurons elicits common and distinct behavioral responses.
(A, D, E) Percent time flies spent performing antennal grooming (A), wing flapping (D), or backward locomotion (E) with optogenetic activation of JONs targeted by JO-C/E-1, JO-C/E-2, JO-F-1, and JO-F-2. Control flies do not express CsChrimson in JONs. Bottom and top of the boxes indicate the first and third quartiles respectively; median is the red line; whiskers show the upper and lower 1.5 IQR; red dots are data outliers. N ≥ 10 flies for each box; asterisks indicate *p<0.05, **p<0.001, ***p<0.0001, Kruskal–Wallis and post-hoc Mann–Whitney U pairwise tests with Bonferroni correction. Figure 6—source data 1 contains numerical data used for producing each box plot. (B) Ethograms of manually scored videos show the behaviors elicited with red-light induced optogenetic activation. Ethograms of individual flies are stacked on top of each other. The behaviors performed are indicated in different colors, including antennal grooming (magenta), wing flapping (gray), and backward locomotion (black). Light gray bars indicate the period where a red-light stimulus was delivered (5 s). (C) Histograms show the fraction of flies that performed each behavior in one-second time bins. Note that only JO-C/E-1 and −2 elicited wing flapping, which was not mutually exclusive with grooming. Therefore, an extra row of wing flapping ethograms and histograms is shown for those lines. See Video 2, Video 3, and Video 4 for representative examples.
