Data are mean±SEM of latency to enter dark (A, G), time spent in the light side of the box (B, H) and the total number of transitions made between the light and dark sides of the box (C, I) in young (left panel) and aged (right panel) control and vinclozolin generation rats. For young and aged female rats N = 8–9/group. For B aged: t15 = 2.65, p<0.018. * P<0.05, compared with control. Performance in the elevated plus-maze in young and aged third-generation female and male rats. Data are mean±SEM of percent open arm time (D, J), percent open arm entries (E, K) and total entries (F, L) in young (left panel) and aged (right panel) control and vinclozolin generation rats. For young rats, all animals from above are shown; for aged rats, N = 5 (control) and 7 (vinclozolin). The aged group represents a subset of those run in the light:dark box shown because of technical (unstable lighting) conditions during testing for the first 5 rats; these rats were omitted from the analysis. For D young: t15 = 2.30, p<0.036. For E young: t15 = 2.51, p<0.024. For D aged: t10 = 2.40, p<0.037. For E aged: t10 = 2.82, p<0.018. *P<0.05, compared with control. For young male rats, N = 9–12/group. For aged male rats, N = 9–10/group. For H young: t19 = −2.65, p<0.016. For I young: t19 = −2.46, p<0.024. * P<0.05, compared with control. All young male animals L: t19 = −3.32, p<0.004. *P<0.05, compared with control.
