a, Electron microscopy (EM) reconstruction images of single pIP10, pMP2, dPR1 and TN1A neurons. b, Synaptic connectivity matrix among pIP10, pMP2, dPR1 and TN1A neurons. TN1A neurons can be separated into two populations (TN1A-1 and TN1A-2) based on connectivity. c, Expression pattern of the TN1A-2 split-Gal4 (left) and the overlaid EM reconstruction images of TN1A-2 (middle) and TN1A-1 (right) neurons. Arrows indicate the neurites that were present in the TN1A-2 split-Gal4 and TN1A-2 neuron images but not in TN1A-1 neuron images. Scale bars, 50 μm. d, Histogram of the number of synapses from upstream neurons onto a dPR1 neuron (body ID: 10300). Only neurons with 50 or more synapses onto dPR1 are shown. e,f, Same as d but for a TN1A-1 (body ID: 15521) (e) and a TN1A-2 (body ID: 13928) (f) neuron. g, Model of pulse and sine song production.
