Time lines for Experiments 1 and 2. The numbers on the preterm and term lines indicate postnatal days, whereas the numbers on the postconceptional age (PCA) line indicate postconceptional age, starting at day 106. The 12‐day difference in birth age between the groups is shown as “−12” on the line for term pigs. The T‐maze test was performed only for pigs in Experiment 1. Tissue sampling was done only for pigs from Experiment 2.
