Lmo4gt/+ and WT mice show similar cue–reward learning. A, WT and Lmo4gt/+ mice increased head entry rates during presentation of the cue and decreased head entry rates during the intertrial interval ITI (*p = 0.006; #p = 0.02; ##p = 0.01 by Bonferroni test; n = 15 WT, n = 18 Lmo4gt/+ mice). B, Latency for head entries into the reward port after cue onset decreased over time in both groups. *p = 0.048, Bonferroni test. C, During goal tracking, both genotypes increased head entries during presentation of the cue. D, Within-session extinction of goal tracking was similar in both genotypes.
