ScerGAL4amn-NP7177 drives expression in mushroom body extrinsic neurons, including the mushroom body anterior inferior medial cell and dopaminergic PAM neurons 13 and 14, that innervate mushroom body gamma lobe slice 3, mushroom body gamma lobe slice 4, mushroom body gamma lobe slice 5, mushroom body beta' lobe slice 1 and mushroom body beta' lobe slice 2. Expression partially overlaps with that driven by EcollexAGMR24E12 in 11 dopaminergic PAM neurons 13 and 14.
Projections of the mushroom body anterior inferior medial neurons innervate the anterior stratum of the beta' lobe segment 1, and/or throughout the middle and posterior strata of segment 2.
Inhibition (using Hsap\KCNJ2UAS.EGFP) of Scer\GAL4NP7177 neurons, in combination with a Gal80[ts] transgene to restrict expression to 1 day prior to training and testing, significanlty improves 3 hour aversive olfactory memory, but not immediate short term memory, compared to controls; 3 hour memory following a 2 min cold shock is similar to that of controls; there is no effect on shock reactivity or olfactory acuity, compared to controls.
