Mean values with standard deviation are shown for Fig. 1. Brain weight-to-body weight and brain volume-to-body weight ratios are provided for each cohort 1-week (postnatal day 14) and 5–7 weeks (postnatal days 42–56) post exposure. Values for unexposed, naïve controls on postnatal day 7 are also listed.
