A, Mutant and control animals reared at 18°C do not exhibit significant differences in perception of the US–90 V or the CS [benzaldehyde (BNZ) and 3–octanol-(OCT)] used for olfactory conditioning. Additionally, there are no significant differences in perception of a highly diluted attractive odor [geraniol (GER)]. Performance of the animals in these tasks was measured by the performance index calculated as by Skoulakis and Davis (1996) and are shown as PI ± SEM. Thus, rearing the animals at 18°C and the lack of LEO in the mushroom bodies do not precipitate sensory deficits. n > 7 for 90V and BNZ, OCT avoidance, but n > 10 for attraction to GER.
B, The performance (PI ± SEM) of control animals and lethal homozygotes and heteroallelics obtained with protocol HS B in avoidance of the US (90 V) and the CS (BNZ, OCT) is not significantly different, indicating that the nearly total lack of LEO from the mutants does not affect their sensory systems requisite for conditioning.n > 7 for all stocks. In addition, lack of LEO does not alter the attraction of lethal homozygotes and heteroallelics toward diluted geraniol, indicating that lack of LEO does affect odor perception. n > 12.
