NTRK2 and memory impairment: We observed a memory impairment in the s-SOR version of the task (paired t-test, p = 0.0005, t = 4.995) (Figure 4C), but not in the d-SOR version (paired t-test, p = 0.7462, t = 0.3337) (Figure 4F), Thus, blocking TrkB only generated a deficit in the “similar” condition, disabling animal’s capacity of discrimination of overlapping memories.
