Odor-evoked responses at the MBON postsynapse. Heatmaps show false-color coded ΔF/F0 values over time, measured in each of the γ-lobe MBONs ((a) MBON-γ1pedc > α/β; (b) MBON-γ2α’1; (c) MBON-γ3 and MBON-γ3β’1; (d) MBON-γ4 > γ1γ2; (e) MBON-γ5β’2a and MBON-β’2mp). Each row corresponds to a recording of an individual neuron in an individual fly in response to a single odor presentation. Values above heatmaps show the percentage of flies that showed a response to that odor in each MBON. Grey bars indicate the odor delivery period. For (a, c–e), n = 29; for (b), n = 30. Schematic diagrams and single frame in vivo functional imaging examples on the left show the dendritic region of each MBON that was imaged. The green dotted line shows the region that was quantified.
