(a) Body weight, (b) brain weight and (c) brain- to body-weight ratio on postnatal day (PND) 1 as well as (d) body weight, (e) brain weight and (f) brain- to body-weight ratio on PND 12. For detailed offspring number information see methods section. C, control offspring after unimpaired gestation; LP, offspring after low-protein diet throughout gestation; LIG, offspring after bilateral uterine vessel ligation; IUS, offspring after intrauterine stress through “sham” operation. Values are expressed as mean ± standard deviation. In case of significance compared to C, adjusted p-values (Mann–Whitney tests) are indicated above the bars; ns, not significant.
