The following movies show odor responses of local neurons, sensory neurons and projection neurons of Drosophila melanogaster measured in the antennal lobes. Neurons were labeled with the calcium sensor G-CaMP using the Gal4:UAS expression system. Movies show responses to three odors (isopentyl acetate, 1-butanol and propionic acid) over a concentration range covering 5 log units (10-7 to 10-2).
Films were acquired at 3 Hz. The red square on the upper left corner of each film indicates the time of stimulation. All movies are scaled to their individual minimum and maximum - see below for the color scale, where the black line indicates no fluorescence change.
