Spontaneous recovery from habituation does not depend on PKA activity. A, Groups of animals were injected (1 μl into the hemolymph) 15 min before habituation with either PBS or PBS containing 500 μm BrcAMP. Using the indicated ISI, different groups of animals were habituated until the criterion of five failures was met. After 2 min recovery, the same animals receive a second habituation session by stimulating the same antenna. The values present the mean ± SEM of stimuli necessary to attain the criterion in the first habituation session (left) and the second habituation session (right). The number of animals is indicated in thebars. First habituation session: ANOVA,p < 0.0001; values indicated with differentletters significantly differ from each other (p < 0.001 unpaired t test). Means of the first habituation session significantly differ from that of the corresponding second habituation session (ANOVA with repeated measures: p < 0.0001; p < 0.0001, paired t test). B, For each animal, the number of stimuli required for habituation in the second habituation session is proportional to the number of stimuli necessary for the first habituation session. (ANOVA, p = 0.83).
