(A) The output neurons from the γ3 mushroom body compartment, visualized by MBONMB083C-Gal4-driven GFP. Brp labels synaptic terminals, allowing the mushroom body visualization (outlined). Scale bar: 100 μm. (B) Arousability from sleep when MBONMB083C are inhibited (green) or activated (yellow). (C) Activity of MBONMB083C neurons on regular vs peptone-supplemented food. (D) Arousability from sleep on regular vs protein-supplemented food. Green outline, flies in which MBONMB083C neurons are silenced. (E) Arousability from sleep when different dopamine receptors are depleted from MBONMB083C neurons. (F) Model. Error bars, mean and S.E.M. Genotypes, sample sizes, and statistical analyses, Table S3.
