Fig 4. Calcium traces of the MGC glomeruli (cum, dmp, dma) during stimulation with a combination of sunflower/ylang-ylang and pheromones.

Both plant blends were presented 6 times in an alternated sequence (see methods) to each animal. One group experienced pairing of sunflower with pheromones and ylang-ylang as unpaired (top row, A), while in the other group ylang-ylang was pheromone-paired and sunflower was unpaired (bottom row, B). All traces show mean ± SE for n = 8 and n = 5 ALs in the 2 groups, respectively. The grey column indicates stimulus window, and colored integers indicate repetition aligned with either the max or min of each trace, depending on whether the signal was excitatory or inhibitory.
