LI in conditioned active avoidance learning. Acquisition of the conditioned avoidance response across 10 blocks of 10 trials conducted 24 h after tone pre-exposure in mutants (left) relative to controls (right). Learning was indexed by the percentage of avoidance trials. Increasing percent avoidance trials indicated the acquisition of avoidance learning as training progressed. The mean percentage of avoidance trials across the 10 blocks is illustrated in the histogram. PE and nPE refers to pre-exposed and non-pre-exposed animals, respectively. All values refer to mean ± standard error of the mean (SEM).
