Fig. 5. Percentage change in search responses to the aversively conditioned odor CS+ (crab odor, CO) and the novel non-conditioned odors (inverse crab odor, ICO; shrimp odor, SO; mullet odor, MO) following an aversive conditioning with generalization testing (protocol of Table 2) in intact lobsters, aesthetasc-ablated lobsters and non-aesthetasc-ablated lobsters. For each group of lobsters, the percentage change in search responses to an odorant following conditioning is the percentage difference between responses of conditioned lobsters and unconditioned lobsters relative to responses of unconditioned lobsters. Data are from Fig. 4.
