Fig. 2. Lesion mice reach control performance with training on the maximum separation/short delay variant of TUNL.

(a) Lesion mice initially performed significantly worse than control on the initial acquisition of the TUNL with maximum separation (≥4 spaces apart) and a 1 sec delay but readily attained similar performance levels by block 2. (b) Lesion animals had significantly faster reaction times during the sample and choice phases across the problem, but no significant differences in latency to retrieve reward. n = 8/treatment. *p<.05.
