The Emotional Connection between Mother and Fetus: A Study on Maternal–Fetal Emotional Synchronization

IntroductIonThe intrauterine environment is now widely recognized as a critical foundation for lifelong neurodevelopmental outcomes.Central to this understanding is the Developmental Origins of Health and Disease (DOHaD) hypothesis, which posits that prenatal exposures-particularly, maternal emotional states-can shape the trajectory of mental health and neurobehavioral development. [1][2][3][4]4]21,22 While this idea was once supported primarily by anecdotal accounts, recent advances in neuroimaging, fetal hemodynamic analysis, and behavioral monitoring provide compelling empirical support.Within this emerging framework, we introduce the concept of intrauterine emotional synchrony: A dynamic, real-time alignment between maternal emotional states and fetal responses across three integrated domains-physiological [e.g., changes in fetal heart rate (FHR) and cerebral blood flow], behavioral (e.g.
