The nervous system is particularly affected with functional retardation in infants and young adults. In addition, even if in some cases no damage appears evident in the beginning of life, correlations have been shown between B-vitamin metabolism and neurodegenerative diseases. However, despite the usual treatment based on B-vitamin injections, the neurological outcomes remain poorly rescued in the majority of cases, compared with physiological functions. In this study, we explored whether a neonatal stimulation of neurogenesis could compensate atrophy of specific brain areas such as the hippocampus, in the case of B-vitamin deficiency. Using a physiological mild transient hypoxia within the first 24 h after birth, rat-pups, submitted or not to neonatal B-vitamin deficiency, were followed until 330-days-of-age for their cognitive capacities and their hippocampus status. Our results showed a gender effect since females were more affected than males by the deficiency, showing a persistent low body weight and poor cognitive performance to exit a maze. Nevertheless, the neonatal stimulation of neurogenesis with hypoxia rescued the maze performance during adulthood without modifying physiological markers, such as body weight and circulating homocysteine. Our findings were reinforced by an increase of several markers at 330-days-of-age in hypoxic animals, such as Ammon\u2019s Horn 1hippocampus (CA1) thickness and the expression of key actors of synaptic dynamic, such as the NMDA-receptor-1 (NMDAR1) and the post-synaptic-density-95 (PSD-95). We have not focused our conclusion on the neonatal hypoxia as a putative treatment, but we have discussed that, in the case of neurologic retardation associated with a reduced B-vitamin status, stimulation of the latent neurogenesis in infants could ameliorate their quality of life during their lifespan.<\/jats:p>","DOI":"10.3390\/ijms21218008","type":"journal-article","created":{"date-parts":[[2020,10,28]],"date-time":"2020-10-28T11:43:06Z","timestamp":1603885386000},"page":"8008","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["The Stimulation of Neurogenesis Improves the Cognitive Status of Aging Rats Subjected to Gestational and Perinatal Deficiency of B9\u201312 Vitamins"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0452-5026","authenticated-orcid":false,"given":"Gr\u00e9gory","family":"Pouri\u00e9","sequence":"first","affiliation":[{"name":"Facult\u00e9 de M\u00e9decine, INSERM 1256\/University of Lorraine, F-54500 Vandoeuvre-les-Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolas","family":"Martin","sequence":"additional","affiliation":[{"name":"Facult\u00e9 de M\u00e9decine, INSERM 1256\/University of Lorraine, F-54500 Vandoeuvre-les-Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Luc","family":"Daval","sequence":"additional","affiliation":[{"name":"Facult\u00e9 de M\u00e9decine, INSERM 1256\/University of Lorraine, F-54500 Vandoeuvre-les-Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Marc","family":"Alberto","sequence":"additional","affiliation":[{"name":"Facult\u00e9 de M\u00e9decine, INSERM 1256\/University of Lorraine, F-54500 Vandoeuvre-les-Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8591-0721","authenticated-orcid":false,"given":"R\u00e9my","family":"Umoret","sequence":"additional","affiliation":[{"name":"Facult\u00e9 de M\u00e9decine, INSERM 1256\/University of Lorraine, F-54500 Vandoeuvre-les-Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5067-042X","authenticated-orcid":false,"given":"Jean-Louis","family":"Gu\u00e9ant","sequence":"additional","affiliation":[{"name":"Facult\u00e9 de M\u00e9decine, INSERM 1256\/University of Lorraine, F-54500 Vandoeuvre-les-Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carine","family":"Bossenmeyer-Pouri\u00e9","sequence":"additional","affiliation":[{"name":"Facult\u00e9 de M\u00e9decine, INSERM 1256\/University of Lorraine, F-54500 Vandoeuvre-les-Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"439","DOI":"10.3171\/2018.5.PEDS17584","article-title":"Twenty years\u2019 experience with myelomeningocele management at a single institution: Lessons learned","volume":"224","author":"Kellogg","year":"2018","journal-title":"J.
