Blocking MB and F5 output simultaneously abolished memory retrieval in cross-modal SP. A, Gal4-driven GFP expression in the three driver lines. Ai–iii, The GFP signal (green) and the specimen labeled by the anti-nc82 antibody (magenta) were excited at 488 and 561 nm, respectively. The (247,c205)-Gal4 labeled both MBs and F5. All images were superimposed confocal sections. FB, Fan-shaped body. Scale bars: 50 μm. B, D, Blocking synaptic output from (247,c205)-Gal4 neurons impaired memory retrieval in both the olfaction → vision and vision → olfaction subsequences of cross-modal SP paradigms at the RT. C, E, Control experiments for B and D, respectively; each bar represents the mean PI in the test section. Error bars are SEM. *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001.
