Fig 1. Schematics of paradigms and experimental design.

Depiction of the first and second session of T-Maze experiments (A) and CPP experiments (B). The drawings show a single replicate for each first session. Sometimes, flies from different replicates were added to reach the minimum amount of flies required for a second session. This was especially the case for Elevator+Dark Tube in the T-Maze (A), and Tubes 0, 1 and 2 in the CPP (B).
