This scoping review synthesizes current research across psychological, physiological, immunological, genetic, and cellular domains to map the \u201ccommunicatome\u201d that orchestrates pregnancy and programs lifelong health. Centrally, we examine the coupling of maternal and fetal heart rate variability (HRV), a paradigmatic manifestation of network physiology in which maternal autonomic oscillations are mirrored in umbilical venous and ductus venosus blood flow to modulate fetal neurodevelopment. We conclude that the decoupling of this physiological network\u2014detectable through integrated biosignal analysis\u2014serves as a critical early-warning marker for pregnancy pathologies, including pre-eclampsia (PE), fetal growth restriction (FGR), and preterm birth (PTB). Furthermore, the review highlights the active nature of fetal\u2013maternal interactions, in which fetal trophoblasts \u201ceducate\u201d the maternal immune system to ensure semi-allogeneic tolerance, and microchimeric cells establish a biological legacy that persists for decades postpartum. Psychologically, prenatal attachment is shown to be a transgenerational process in which the quality of current relationship care mediates the transmission of ancestral parenting patterns. By framing these interactions through the Developmental Origins of Health and Disease, we conclude that the decoupling of this physiological network\u2014detectable through integrated biosignal analysis\u2014serves as a critical early-warning marker for pregnancy pathologies and neurodevelopmental vulnerabilities.<\/jats:p>","DOI":"10.3389\/fnetp.2026.1864981","type":"journal-article","created":{"date-parts":[[2026,9,7]],"date-time":"2026-09-07T07:47:27Z","timestamp":1788767247000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["The maternal\u2013fetal communicatome: a scoping review and network physiology perspective on a unified, adaptive, and multiscale interaction network"],"prefix":"10.3389","volume":"6","author":[{"given":"Igor V.","family":"Lakhno","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Kharkiv National Medical University","place":["Kharkiv, Ukraine"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,7]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"244","DOI":"10.1515\/jpm-2025-0289","article-title":"Nutriepigenomics in perinatal medicine: maternal nutrition as a modulator of fetal gene expression and long-term health","volume":"54","author":"Andonotopo","year":"2025","journal-title":"J.
