Ca²⁺-transients in flies with disturbed GABA_BR or G-proteins within the ORNs. (A) Response profiles of CGP54626-treated flies (A-C), Or83b,GA/GABA_BR2-RNAi (GBi) (D-F), or Or83b,GA/UAS-PTX flies (G-I) to 5 s application of spearmint, citronella, or octanol, applied 5 times at 5 min-intervals. The amplitudes of activity during the repeated stimulations do not decrease for CGP54626, for the 3 odors, while they are reduced to a large extent for GBi or UAS-PTX flies. (J-L) Mean of total photons for each condition. (M-O) Mean of duration of the response (s). n = 5-9 flies for each condition. Values are means +/-SEM. Statistics: same tests as for Figure 2 (see Table 1 for statistical values).
