Neuroimaging procedures were previously described (17 (link)) and are repeated in detail below to maintain continuity of methods descriptions within a study. At 30 d of age, pigs were subjected to MRI scanning procedures. Before scanning, pigs were anesthetized via an intramuscular injection of Telazol (0.07 mg/kg body weight; Zoetis). Pigs were immediately transferred to the MRI machine in which they were maintained on an average of 2% isoflurane:98% oxygen for the duration of the 60-min scan. Pig heart rate and peripheral capillary oxygen saturation were monitored throughout the duration of the scanning session with the use of an MRI-compatible pulse oximeter. MRI procedures, along with postimaging analyses of brain region volume and diffusion tensor imaging, were previously described (21 (link)). Pigs were scanned with the use of a Siemens MAGNETOM Trio 3T Imager with a Siemens 12-channel head coil. Upon completion of MRI scans, pigs were allowed to recover from anesthesia, vital signs were monitored every 15 min until complete recovery, and pigs were subsequently transported back to the rearing facilities.
