Figure 1. The aru^8–128 allele reduces place memory performance.

Wild-type CS and Berlin (B) flies, as well as aru^8–128 flies in either the CS or B genetic backgrounds were trained for 20 min and then examined for place memory directly afterward. The mutant memory performance was statistically different from wild-type only in the CS genetic background (CS vs. aru^8–128 (CS), ** = p<0.01, N = 215; Berlin vs. aru^8–128 (B), p>0.1, N = 643). The values are means and error bars represent SEMs.
