Figure 4. Tubb2b^brdp/+ heterozygous mice exhibit cued trials.

MWM cued random trials as a test of proximal cue learning (latency, s). There was a significant genotype effect but no interaction. The effect is shown on the same scale as latency in Figure 1 for comparison. As can be seen the latency effect on cued trials was small and did not change across days. **p < 0.01 vs. WT. WT: n = 18 mice; Tubb2b^brdp/+: n = 18 mice (1 litter was inadvertently missed)
