Figure 2. PPL1 neurons are required for aversive taste memory.

Figure 2

A) Mean PER suppression for PPL1 expressing lines during testing shows impaired PER suppression in flies expressing TRPA1 and tested at 32°C (pink) compared to controls harboring split-GAL4 constructs alone (black) or tested at 25°C (cyan). (n=10–56). B) Aversive taste memory was disrupted when four lines that express in the PPL1 cluster of DANs were silenced. MB060B (n=10–29), MB065B (n=12–56), MB502B (n=10–27), MB504B (n=10–36)(p<0.05). Lower panels: Innervation patterns of PPL1 neurons in MB lobes visualized with pJFRC225-5xUAS-IVS-myr:: smGFP-FLAG reporter in VK00005.. Scale bar represents 20µm. C) Specific expression of identified PPL1 DANs. Only the MB-V1 and MB-α3 clusters are present in all the identified lines. (The gray scale represents subjectively determined intensity of terminals in the MB). All data represent the mean ± SEM, * p<0.05, ** p<0.01, *** p<0.001
