Connectivity-based classes and spatial distributions. (A) Total number of connectivity-based classes innervating each of the 75 neuropil regions, mapped using the natverse 3D template (Bates et al., 2020) of the Drosophila brain. Supporting Information Figure S2 illustrates in detail the 3D embedding of each connectivity-based class, along with its constituent neurons and innervating neuropils. (B) Class 2, an example of spatially compact class. (C) Class 50, an example of spatially extensive class. Each neuron is assigned a random color for easier distinguishability.
