ScerGAL4GMR76B09 drives expression in mushroom body extrinsic neurons, including mushroom body output neuron 5 and mushroom body medial-vertical lobe arborizing neuron 2, that innervate mushroom body gamma lobe slices 1, 2 and 4, mushroom body beta lobe slice 1, and mushroom body alpha lobe slices 1, 2 and 3. Expression overlaps with that driven by EcollexAGMR24E12 in mushroom body output neuron 5.
