Atlas of the MBE neurons. Identification of the MBE neurons by compartment innervation, input and output regions, and cell body location. The MBE of only one hemisphere is shown (for the segmentally homologous, unpaired OAN-a1 and OAN-a2 neurons the cell bodies are located at the midline). For MBE pairs, the second neuron of the pair is indicated by its cell body and stippled primary neurite. Anatomical panels show z-projections of those parts of the larval brain that include the respective MBE. MBEs are visible based on antibody staining against the flp-out effectors; anti-neuroglian staining in gray reveals the local brain structure. Note that the nomenclature for the MBIN-l1 and MBON-p1 neuron is based on their compartment innervation in the stage 1 larva (Supplementary Fig. 1). For more details, see Supplementary Table 1
