Figure 1

Time course of memory performance in the wild-type strain C-S (K), mutant nemy (P153 stock) and two other P insertional stocks from the same collection after 30-min training with a fertilized female. A. Results of the retention test (with an ether-immobilized virgin female). B. Results of the retraining test (with a mobile fertilized female). Performance index (PI) is a measure of courtship inhibition resulted from training (see Methods). Because its calculation is based on comparison of mean courtship indices for independent samples of naive and trained males, no standard errors are presented. The markers are filled in when mean courtship index of naive males is significantly higher than mean courtship index of trained males (one-sided t test, P < 0.05). This is equivalent to testing the null-hypothesis PI = 0 against the alternative PI > 0. Sample size is about 20 naive and 20 trained males for each PI value.
