The deprivation of the REM sleep phase during uterine life can lead to altered cortical and brainstem development and to the supersensitivity to the noradrenaline of the pyramidal cells in the hippocampus, impairing the receptors' sensitivity (Mirmiran et al., 2003).

L., and O'Brien, L. M. (2018). Our current clinical management of fetal and maternal health is not individualized and intermittent, suffering from a pattern of catching up with clinical symptoms instead of using biometric data to predict and steer developmental trajectories and health outcomes for the pregnant mother and her fetus during the delivery and after to their fullest potential. Heart rate variability analysis can give paramount hints about the fetus' or newborn's well-being and allow clinicians to predict the occurrence of even deadly complications (Table 1) (Stone et al., 2013; Al-Shargabi et al., 2017; Massaro et al., 2017; Chiera et al., 2020; Frasch, 2020). However, when late decels occur in more than 50 percent of the contractions of your uterus, then fetal hypoxia is a plausible explanation. (2009). 34, 681692. What Do Contractions Feel Like? Autonomic responses of premature newborns to body position and environmental noise in the neonatal intensive care unit. Biol. This increases the flow of deoxygenated blood to your heart and body, including your uterus and placenta.

Lastly, even electromagnetic field (EMF) radiations during pregnancy, due to overexposure to mobile phones, diagnostic instruments, or occupation, seem to be a risk factor for preterm delivery (Rou et al., 2016) and to have effects on ANS development (Rezk et al., 2008). fHRV undergoes fewer changes with the use of the full lateral position, compared with the use of wedged supine position (Preston et al., 1993).

Believed to be an abnormal FHR pattern, late decelerations indicate a reduction in heart rate, usually after a uterine contraction. Sci. Statistically, severe fetal acidemia (pH < 7.00) has been shown to occur in between 0.5 and 10% of human births. Although the induction of the hormone oxytocin has no cardiac repercussions, it can still influence the development of the vagus nerve and the ANS in the last hours of labor. Even early prenatal exposure to the virus, indeed, seems to create a chronic hypoxic environment to the fetus, affecting vagus nerve developmental patterns, and imprinting postnatally the ANS cardiac pacemaker activity (Herry et al., 2021). Am J Obstet Gynecol. Early exposure of buprenorphine induces higher levels of fHRV, whereas at 3236 GWA fetuses display less suppression of motor activity (Jansson et al., 2011; Conradt et al., 2018), indicating the involvement of the vagus nerve system. Several studies have also shown a major change in fHRV in women given an analgesic agent such as lidocaine (Boehm et al., 1975; Lavin, 1982). Opioids are often used as analgesic therapy during labor.

In this sense, dysregulations in mother circadian rhythm, due to disturbed sleep-awake patterns, could interfere with the development of circadian control systems of the fetus and, consequently, with the circadian profile of the vagus nerve, impacting the physiologic vagal neurodevelopment itself.

Samueloff A, Langer O, Berkus M, Field N, Xenakis E, Ridgway L. Is fetal heart rate variability a good predictor of fetal outcome? A., Drogtrop, A. P., Gyselaers, W. J. The variations in ambient and core temperature appear to impact newborns HRV (Massaro et al., 2017): in particular, extreme variations seem to affect the autoregulatory capacities of the cardiac system and, consequently, HRV, possibly due to a dysregulated release of excitatory neurotransmitters (Tsuda et al., 2018). Maternal nutrition is a substantial part of the developmental or metabolic programming of newborns (Koletzko et al., 2018, 2019), with short- and long-term consequences on health and a relevant impact on fetoplacental growth patterns (Morrison and Regnault, 2016). The occlusions resulted in fetal hypertension and vagally mediated decelerations. doi: 10.1523/JNEUROSCI.09-05-01764.1989, Tsuda, K., Iwata, S., Mukai, T., Shibasaki, J., Takeuchi, A., Ioroi, T., et al.

Gynecol. Res. Moreover, some studies have highlighted that the same factors can differently affect development based on the exposure period (i.e., early vs. late gestation) (Schulz, 2010; Gartstein and Skinner, 2018; Kasahara et al., 2020, 2021).

Ontogeny of reticular framework of white pulp and marginal zone in human spleen: immunohistochemical studies of fetal spleens from the 17th to 40th week of gestation. In this sense, hormones may play a crucial etiological role, as literature shows that gonadal hormones have a significant impact on the sex-dependent differentiation of the entire nervous system (Chung and Auger, 2013). 25, 236247. Clin. Fetal chemoreception: a developing story. Dev. Due to the negative consequences ANS impairment can have later in life, it is paramount to rely on any protective factor that can sustain ANS maturation, starting from taking care of maternal health and lifestyle, which can greatly affect fetal development and, then, breastfeeding. A variety of different ANS and vagus nerve pattern activities are now well-established between different sexes, which can be well-represented by HRV tracking even during fetal life. Indeed, several studies have shown the vagus nerve is involved in many vital processes during fetal, perinatal, and postnatal life: from the regulation of inflammation through the CAP, which may affect each organ (Herry et al., 2019; Frasch, 2020), to the production of hormones involved in bioenergetic metabolism (Bystrova, 2009).

Luckily, applying gentle touch, an intervention that stimulates the vagus nerve via C-tactile fibers, to medical care has the potential to regulate ANS function (Manzotti et al., 2019) and, thus, it is conceivable it could have protective effects on sleep. Prenatal alcohol exposure and fetal programming: effects on neuroendocrine and immune function. Early Hum. It is worth remembering that the two ANS branches are anything but antagonists: in fact, the regulation of many organic functions (Goldstein, 2006), including the immune and inflammatory responses (Bonaz et al., 2021), strictly depends on the synergy between the two branches. 16, 483488. Since the placental microbiome could also affect metabolic pathways, thus leading to a pro-inflammatory environment (Gomez-Arango et al., 2017; Fischer et al., 2019), it could also affect the ANS and vagus development of the fetus. The degree of hypertension and the amount of deceleration were closely related, although some deceleration remained when the transient hypertension was prevented by adrenergic blockade.

The cardioregulatory center in the medulla oblongata contains an acceleratory center and an inhibitory center. A study of fetal heart rate acceleration patterns. Even if the light-dark cycle does not seem to significantly affect the fetal circadian rhythm, there are age-dependent fHRV patterns after transabdominal fetal stimulation with halogen light, similarly to the VAS (Peleg and Goldman, 1980), which seem increasingly definite in the later stages of pregnancy, when the fetal optic pathways and ANS control on the cardiac activity reach maturity (Thanaboonyawat et al., 2006).
