A Mapping analysis of all the sensilla following stimulation with 5% saponin in control and Gr28bMi flies (we followed Tanimura's nomenclature) (n ≥ 8). The error bars represent SEMs. The asterisks indicate significant differences from that of the control detected by a single-factor ANOVA with Scheffe's analysis to compare two sets of data (*P < 0.05, **P < 0.01).
