The ortC1a enhancer and hs43 mini-promoter regulate expression of a lexA::VP16 driver.
Inhibition (using Ctet\tetXTNT-LC.13x.lexAop.Tag:HA) of Ecol\lexAVP16.ort.C1a cells in adults results in a significant reduction in short-term aversive visual (blue/green) memory, compared to controls, with no effect on the optomotor response to blue-green patterns.
