Moreover, when comparing the data for the mice in the two age groups, we found a significant correlation ( p = 0.0205) and a highly significant correlation ( p < 0.0001) between the number of mature neurons and their escape latencies on day 6 of rMWM, and on days 9 and 10 of cdMWM, respectively, in individual 14MO mice but not in 6MO mice.
