Description

The R20G03 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.

Thermogenetic activation (using TrpA1UAS.(B).cKa at 28.5[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R19F09 and Hsap\RELAAD.R20G03 in adult males does not significantly affect 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.R19F09 and Hsap\RELAAD.R20G03 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, but not shi1.UAS, at 32[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R19F09 and Hsap\RELAAD.R20G03 in adults during training, consolidation and testing substantially reduces aversive 2 h associative olfactory memory, compared to controls; inhibition (using shits1.IVS.p10.20xUAS or shi1.UAS, at 32[o]C) substantially reduces attractive 2 h associative olfactory memory, compared to controls, with no effect on naive sugar attraction. Inhibition of these neurons (using shits1.IVS.p10.20xUAS at 31-33[o]C) during training, consolidation and testing does not significantly affect appetitive 1 min associative visual memory, compared to controls; inhibition during testing alone does not significantly reduce aversive 24 h associative olfactory memory, compared to controls; inhibition during training and testing significantly reduces 24 h appetitive (to the extent that this is aversive), but not 30 min aversive, associative olfactory memory towards ethanol, compared to controls.

Thermogenetic activation (using TrpA1UAS.(B).cKa at 28.5[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R19F09 and Hsap\RELAAD.R20G03 in adults does not significantly affect sleep, compared to controls, and there is no effect on social or locomotor behaviors.
