This issue introduces the reader to a range of important issues that involve neonatal encephalopathy: from different animal models to neuroprotection and clinical biomarkers. The collection of papers is important because the reader obtains a bird’s eye view of the landscape of perinatal brain injury, and also, the various nuances in dealing with translational and clinical issues.Robinson and colleagues report on the beneficial effects of postnatal intraperitoneal erythropoietin administration on adult cognitive deficits in a rat model of placental insufficiency (Robinson et al., 2021). This article is notable not only for focusing on functional outcomes, but also for focusing on adult cognitive outcomes after a prenatal insult. Furthermore, the proper use of touch screen technique to test the animal behavior and cognitive function is presented. The translational implication of adult outcomes suggests that the 5-year cycles of NIH funding may make it difficult to establish clear-cut benefits of a promising postnatal neuroprotectant following a prenatal insult. The reader is left to wonder whether the absence of benefit in death or severe neurodevelopmental impairment at 2 years of age in the EPO trial in 24-to 32-week premature infants (Juul et al., 2020) and in the recently published clinical trial of high-dose-erythropoietin-for-asphyxiaand-encephalopathy (HEAL) trial given intravenously (Wu et al., 2022) could be because a longer follow-up period was not possible. Importantly, Robinson’s article uncovers sex differences in adult cognitive outcomes and the deficits in the visual system. To estimate the severity of the 60-min uterine ischemia at E18, the previous publication by the group (Jantzie et al., 2013) mentioned a fetal loss of 23% but did not mention any newborn deaths. A severe prenatal insult would usually result in postnatal deaths. The implication of possibly all newborn survivors reaching adulthood in the present study is that the status of brain injury probably updated to a mild-to-moderate severity at the time of postnatal EPO administration. Also, the dosage used in the Robinson’s article, 2000 U/kg dose ip for 5 consecutive days in P1–P5 rats, is roughly double when compared to that used in the HEAL trial in human newborns, 1000 U/kg iv dose on 1, 2, 3, 4, and 7 days (Wu
