ORN responses to linalool oxide depend on concentration but not air speed. A: sample raw single-sensillum recording (top) showing the responses of the ab2A neuron to 10% linalool oxide at an air speed of 1.4 m/s. In the raw trace, the ab2A neuron corresponds to the large spike waveform (de Bruyne et al. 2001). The stimulus artifact at odor onset and offset is clipped for clarity. Rasters (bottom) show spiking responses at different concentrations and air speeds, with 3 trials per condition. Odor pulse duration is in gray. B: average ORN firing rates (±SE) plotted over time for a low and a high air speed condition (50% linaool oxide, n = 7). C: average ab2A firing rates evoked by linalool oxide (n = 7). D: average ab3A firing rates evoked by linalool oxide (n = 4). Error bars are SE and are sometimes obscured by markers.
