ScerGAL4NP0242 drives expression in mushroom body extrinsic neurons, including medial-vertical lobe arborizing neuron 2, that innervate mushroom body beta lobe slices 1 and 2, and mushroom body alpha lobe slices 1, 2, 3.
Medial-vertical lobe arborizing neuron 2 arborisation within the beta lobe is within segment 1 and 2 of the posterior stratum, and within segment 1 of the middle and anterior strata.
Inhibition (using Hsap\KCNJ2UAS.EGFP) of Scer\GAL4NP0242 neurons, in combination with a Gal80[ts] transgene to restrict expression to 1 day prior to training and testing, does not affect 3 hour aversive olfactory memory, compared to controls.
