Figure 6. Chemotaxis-Dependent Change in Frequency of Pause Turns Is Prevented when Synaptic Activity Is Inhibited in the BL.
(A) The BL driver line is expressed in the olfactory lobe as labeled with anti-GFP.
(B) Representative tracks of larvae crawling under green light in an arena with a central olfac-tory cue. The asterisk indicates the beginning of the track.
(C) Percentage of success. The percentage of larvae that reached the central area of the plate defined by a circle with a 3 cm diameter was quantified. A Fisher's exact test was performed to evaluate differences between the genotypes.
(D) The number of pause turns/min was quantified in concentric areas of different diameters. Thirteen animals of each control group and 17 of the experimental were tested. A Kruskal-Wallis test with Dunn's multiple comparison was performed to evaluate the significance between the different diameters in each of the treatments. a’ means p < 0.05, a” p < 0.001 comparing with < 3cm; b means p < 0.01 and b’ p < 0.05 comparing with 3–5 cm. NS, nonsignificant.
