The GMR71G01 enhancer fragment followed by the Drosophila synthetic core promoter (DSCP) is fused upstream of the GAL4(DBD)::Zip- hemidriver (component of the 'Split GAL4' system, contains the GAL4 DNA-binding domain).

Brief activation of Scer\GAL4AD.R15A01 and Scer\GAL4DBD.R71G01 neurons leads to male flies displaying persistent courtship behavior (tracking and singing) towards a rotating magnet that was previously of no interest.
Thermogenetic activation (using TrpA1UAS.(B).cKa at 29[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R71G01 and Hsap\RELAAD.R15A01 in adult males significantly increases aggressive lunging behavior and wing extensions towards other males, compared to controls.
Optogenetic activation (using Cnoc\ChR1::Csub\ChRCsChrimson.IVS.20xUAS.Venus with 685 nm (red) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R71G01 and Hsap\RELAAD.R15A01 in adult males significantly increases wing extensions towards other males during illumination and significantly increases aggressive lunging behavior towards other males following illumination, compared to controls; locomotor velocity is also significantly reduced during illumination, compared to baseline; activation in solitary males results in a sustained increase in wing extensions during and after illumination, compared to controls.
Optogenetic activation (using Crei\ChR1::Vcar\ChR1::Vcar\ChR2ReaChR.UAS.Citrine with 530 nm (green) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R71G01 and Hsap\RELAAD.R15A01 in adult males significantly increases wing extensions towards other males during illumination and significantly increases aggressive lunging behavior towards other males for at least 10 min following illumination, compared to controls; activation in solitary males results in an increase in wing extensions during and up to 5 min after illumination, compared to controls; for at least 10 min after activation, a solitary male that is introduced to another male will significantly increase aggressive lunging behavior, compared to controls; locomotor velocity is significantly reduced during and up to 1 min following illumination, compared to controls.
Optogenetic activation (using Cnoc\ChR1::Csub\ChRCsChrimson.IVS.20xUAS.Venus with bright white light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R71G01 and Hsap\RELAAD.R15A01 in solitary adult males significantly increases wing extensions, compared to baseline; this increase is significantly reduced when Scer\GAL4GMR43D01 cells are simultaneously activated.
Activation of Scer\GAL4AD.R15A01 and Scer\GAL4DBD.R71G01 neurons triggers wing extension behavior; depending on the combination of UAS and light used, different numbers of flies show this behavior: 0% with blue light activation of Crei\ChR2Scer\UAS.cSa, Crei\ChR2H134R.Scer\UAS.2A.T:Avic\GFP-EYFP or Crei\ChR2C128T.Scer\UAS.T:Avic\GFP-YFP; 0% with red or green light activating Crei\ChR1[C1V1.T-T.Scer\UAS. T:Avic \GFP-EYFP]; 40% (red) or 100% (green) light activating Crei\ChR1ReaChR.Scer\UAS.T:Crei\ChR2,T:Avic\GFP-mCitrine. Social isolation lowers the threshold for Crei\ChR1ReaChR.Scer\UAS.T:Crei\ChR2,T:Avic\GFP-mCitrine-activated male courtship behavior.
