The R64B03 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.

Acute optogenetic activation (using Cnoc\ChR1::Csub\ChRCsChrimson.IVS.20xUAS.Venus with 627 nm (red) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R29G08 and Hsap\RELAAD.R64B03 induces short-lived fast running behavior, unlike controls.
Silencing of L3 lamina neurons, using Hsap\RELAAD.R64B03.T:Zzzz\Zip+, Scer\GAL4DBD.R14B07.T:Zzzz\Zip- and Hsap\KCNJ2Scer\UAS.T:Avic\GFP-EGFP, extends the height of the contrast sensitivity tuning function.
Split-GAL4 transgene, constructed as described in FBrf0212052.
