Description

The R52G04 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.

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.R94B10 and Hsap\RELAAD.R52G04, 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.R94B10 and Hsap\RELAAD.R52G04 during testing, 24 h after spaced, but not massed, training significantly impairs aversive olfactory long term memory in adults, compared to controls.

Blocking synaptic transmission (using shits1.IVS.p10.20xScer\UAS at 33[o]C) from neurons targeted by the split-GAL4 combination of Scer\GAL4DBD.R49F03 and Hsap\RELAAD.R52G04 significantly impairs visual (brightness discrimination conditioning) memory performance, compared to controls; there is no significant effect on memory after aversive color discrimination conditioning.

Blocking synaptic transmission (using shits1.IVS.p10.20xScer\UAS at 33[o]C) from neurons targeted by the split-GAL4 combination of Scer\GAL4DBD.R17C11 and Hsap\RELAAD.R52G04 does not significantly impair visual (brightness discrimination conditioning) memory performance, compared to controls.

Inhibition (using shi1.UAS at 32[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R17C11 and Hsap\RELAAD.R52G04 in adults during, or immediately after, training or during, but not immediately before, testing, significantly impairs long-term appetitive olfactory memory, compared to controls; inhibition does not affect short-term memory.

Thermogenetic activation (using TrpA1UAS.(B).cKa at 30[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R17C11 and Hsap\RELAAD.R52G04 in adults, in combination with a paired odor, results in formation of a significant attractive olfactory long-term memory, 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.R17C11 and Hsap\RELAAD.R52G04, or Scer\GAL4DBD.R94B10 and Hsap\RELAAD.R52G04, in adult males does not significantly affect the amount of sleep, compared to controls; activation significantly increases locomotor activity of awake adult males, compared to controls.

Inhibition (using shits1.IVS.p10.20xUAS at 31.5[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R94B10 and Hsap\RELAAD.R52G04 in adult males 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.R94B10 and Hsap\RELAAD.R52G04 in adult females in an area of an arena significantly increases attraction to that area, compared to controls; there is no effect on angular speed or walking speed, compared to baseline, similar to controls; simultaneous activation of these cells and neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R13F04 and Hsap\RELAAD.R93D10, or Scer\GAL4DBD.R19F09 and Hsap\RELAAD.R25D01, also increases attraction, to a similar extent, or greater extent, respectively, compared to either subset alone.

Inhibition (using shits1.IVS.p10.20xUAS at 31-33[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R94B10 and Hsap\RELAAD.R52G04 in adults during training, consolidation and testing does not substantially reduce aversive or attractive 2 h associative olfactory memory, or aversive or 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 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.R94B10 and Hsap\RELAAD.R52G04 in adults significantly increases sleep, compared to controls, with no effect on social or locomotor behaviors.

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.R17C11 and Hsap\RELAAD.R52G04 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.R17C11 and Hsap\RELAAD.R52G04 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 (using shits1.IVS.p10.20xUAS at 31-33[o]C) does not significantly affect aversive or appetitive 1 min associative visual memory, compared to controls; this inhibition 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 at 28.5[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R17C11 and Hsap\RELAAD.R52G04 in adults does not significantly affect sleep, compared to controls, and there is no effect on social or locomotor behaviors.
