Figure 2From: Dynamics of glutamatergic signaling in the mushroom body of young adult DrosophilaCommonly used mushroom body drivers do not target the last born Kenyon cells just after adult eclosion. (A) In 17d-GAL4; UAS-mCD8::GFP adults just after eclosion, GFP is not present in the inner axons of the α/βc neurons as seen in the lobe (arrow) or in the pedunculus (arrowheads in the insert). (B) Ten days later, all the α/βc KCs express GFP as shown in the lobes and pedunculus (insert). (C, D) Similar observations with the c739-GAL4 driver line that does not express GFP in the α/βc neurons right after eclosion (C), but target all α/β KCs 10 days later (D). sp, spur. (E, F) Similar observations with the 201Y-GAL4 driver line that targets both the α/β and γ neurons. This line does not target the last born α/βc KCs just after eclosion as well. Scale bars: 20 μm.Back to article page
