The R12C11 enhancer fragment is fused upstream of the Drosophila synthetic core promoter (DSCP) followed by the p65(AD)::Zip+ hemidriver (component of a 'split driver' system, contains the p65 activation domain). A Hsp70 transcriptional terminator is present.

Optogenetic activation (using Cnoc\ChR1Cs.IVS.20xUAS.Venus with 660 nm (red) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R20G03 and Hsap\RELAAD.R12C11 in larvae significantly induces rolling behaviors, compared to controls; when optogenetic activation is restricted to small clones of these cells (using hs-FLP to excise a stop codon from Cnoc\ChR1Cs.20xUAS.FRT.Venus to generate Cnoc\ChR1Cs.20xUAS.Venus), activating a single larval abdominal 4 Wave neuron significantly increases forwards locomotion, whereas activating a single larval abdominal 3 Wave neuron significantly increases backwards locomotion, and activation of both of these neurons induces wiggling and bending (rolling behaviors), compared to controls.
Inhibition (using shi1.UAS at 31[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R20G03 and Hsap\RELAAD.R12C11 in larvae significantly reduces the probability of backwards motion in response to a head touch and significantly increases the latency in transit to forwards locomotion, compared to controls, with no effect on the backwards response to blue light.
Blocking protein synthesis (using Rcom\RA[cs2.UAS] at 30[o]C) for the full 24 h between spaced training and testing in neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R14C08 and Hsap\RELAAD.R12C11, significantly impairs aversive olfactory long term memory in adults, compared to controls.
Acute inhibition of endocytosis (using shi1.UAS at 32[o]C) in neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R14C08 and Hsap\RELAAD.R12C11 during testing, 24 h after spaced, but not massed, training significantly impairs aversive olfactory long term memory in adults, compared to controls.
Inhibition of synaptic release (using shits.UAS.cUa at 32[o]C) in neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R14C08 and Hsap\RELAAD.R12C11 significantly reduces carbon dioxide avoidance in starved or fed adults, compared to controls, but the effect is significantly smaller in fed flies.
Optogenetic activation (using Cnoc\ChR1Cs.IVS.20xUAS.Venus with 617 nm (red) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R14C08 and Hsap\RELAAD.R12C11 in adults does not result in significant avoidance of, or attraction to, the illuminated area.
Thermogenetic activation (using TrpA1UAS.(B).cKa at 28.5[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R14C08 and Hsap\RELAAD.R12C11 in adult males significantly reduces the amount of sleep, compared to controls; activation does not significantly affect locomotor activity of awake adult males, compared to controls.
Optogenetic activation (using Cnoc\ChR1::Csub\ChRCsChrimson.IVS.20xUAS.Venus with 617 nm (red) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R14C08 and Hsap\RELAAD.R12C11 in adult females in an area of an arena does not significantly affect time spent in that area, compared to controls.
Inhibition (using shits1.IVS.p10.20xUAS at 31-33[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R14C08 and Hsap\RELAAD.R12C11 in adults during training, consolidation and testing does not substantially reduce aversive 2 h associative olfactory memory, or aversive or appetitive 1 min associative visual memory, compared to controls; inhibition (using shits1.IVS.p10.20xUAS, but not shi1.UAS, at 32[o]C) substantially reduces attractive 2 h associative olfactory memory, compared to controls; inhibition (using shits1.IVS.p10.20xUAS at 31-33[o]C) during testing alone does not significantly reduce aversive 24 h associative olfactory memory, and inhibition only during training and testing does not significantly reduce 24 h appetitive, or 30 min aversive, associative olfactory memory towards ethanol, compared to controls.
Thermogenetic activation (using TrpA1UAS.(B).cKa or TrpA120xUAS.JFRC124 at 28.5[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R14C08 and Hsap\RELAAD.R12C11 in adults significantly reduces sleep, compared to controls, with no effect on social or locomotor behaviors.

FlyBase curator comment: According to correspondence with the authors, some split combinations listed in the methods of the paper are incorrect; the correct combinations (MB002B=R12C11-AD+R14C08-DBD, MB316B=R58E02-AD+R93G08-DBD, MB056B=R76F05-AD+R80G12-DBD, MB047B=R58E02-AD+R93A09-DBD) are listed on FlyLight so these are the ones that have been associated with the paper.
