Comment: expression localized to surface of mushroom body alpha-lobe
Expression is observed in ~500 projection neurons in the surface layer of the α and β lobes of the mushroom body.
Expression is observed in 2-4 projection neurons in antennal glomeruli DM1, VA4 and VC1.
Blocking synaptic transmission (using shi1.Scer\UAS at restrictive temperatures) from Scer\GAL4NP5286 neurons significantly impairs sucrose-reinforced appetitive or electric-shock-reinforced aversive memory performance (3 hours after conditioning) compared to controls. Flies undergo conditioning at a permissive temperature (23[o]C), whereas testing is at a restrictive temperature (33[o]C); there are no significant memory differences when training and testing is at permissive temperatures. Scer\GAL4NP5286>shi1.Scer\UAS flies exhibit normal olfactory acuity at the restrictive temperature.
Blocking synaptic transmission in Scer\GAL4NP5286-expressing neurons for the 12 hour interval 6 hours after spaced training has no effect on aversive long term memory.
Blocking synaptic transmission in Scer\GAL4NP5286-expressing neurons during the post-training period has no effect on appetitive long term memory (association of an odor with sucrose).
