activity along the olfactory pathway.

Drosophila ”.

Figure 1B: Odor and post-odor responses along the olfactory pathway.
Spatial distribution of Ca2+ activity during and after olfactory stimulation (here with 1-butanol) in the neuronal compartments along the olfactory pathway.
Color-coded
DF/F images show the average of 5 s recording time (i.e., 25 frames).
All areas showed distinct responses upon odorant stimulation. (Scale bars 20 µm).
Below, see the calcium imaging movies with different odorant stimulations.
The movies are 35 s long, odorant stimulation starts after 5 s and lasts for 10 s (indicated by a white square in the upper left corner).
