Figure 8.
Innate behaviors of Dp16 versus euploid mice. A, Nest-building ability. Nesting score was assessed from overnight up to 20 d. B, Digging behavior as measured by the number of marbles buried during 6 min. C, D, Spontaneous alternation is normal in Dp16. Measures of spontaneous alternation (C), number of arm entries (D), velocity (E), and distance traveled (F) were unchanged from euploids. In each graph, the bars represent the mean ± SEM (Eu = 11, Dp = 13, *p < 0.05, **p < 0.01).
