Figure 8.

Larvae with two functional OSNs show the same response profiles as larvae with each of the OSNs alone. Electrophysiological activity of OSNs from [Or42a-Gal4/UAS-Or83b; Or83b ^−/−] (“Or42a”), [UAS-Or83b; Or59a-Gal4, Or83b ^−/−] (“Or59a”), and [Or42a-Gal4/UAS- Or83b; Or59a-Gal4, Or83b ^−/−] (“Double Or”) larvae, in response to 1 s presentations of ethyl acetate and anisole. A, Single Or larvae were presented with each odor once and either showed a response or did not. B, Double Or larvae (n = 7) were presented with each odor four times (“repeated presentations”); the mean response consistency is presented for these larvae (±SEM). C, Response consistency of double Or larvae on the first presentation of each odor (“single presentation”).
