FIGURE 2

The effect of complex housing and early life MD on (A) habituation to the 5-choice SRTT chambers as expressed by the number of nose hole entries in blocks of 5 min and (B) speed of learning the 5-choice SRTT as expressed by the number of omissions at the start of each change (decrease) in stimulus duration. Note that at end of training (at stim duration 1.2 s) no group differences exist. Graphs represent mean ± SEM. Standard housing no-MD (n = 8) and MD (n = 8), complex housing no-MD (n = 16) and MD (n = 16).
