ScerGAL4Mz160 labels the mushroom body ventral lobe arborizing neuron 2 alpha. It is also expressed in the optic lobe, a subset of olfactory receptor neurons, the antennal mechanosensory and motor center, the optic tubercle, great commissure, bulb, ventrolateral protocerebrum and surface glia.
Inhibition (using shi1.UAS at 33[o]C) of Scer\GAL4Mz160 cells in adults significantly reduces short term (5 min) aversive olfactory memory, including its anaesthesia-resistant component, compared to controls; inhibition during testing significantly reduces medium term (3 h) aversive olfactory memory, but not its anaesthesia-resistant component, compared to controls, with no effect on long term (24 h after massed training) memory.
