M., Harris, K., Kamiza, S., Harjunmaa, U., Ashorn, U., Nkhoma, M., et al. This affection ultimately interferes with cerebral fetal neurodevelopment, including the nucleus accumbens and hippocampus, that are involved in CAN (Seckl and Meaney, 2004). It could also affect the role of placenta as the immune pacemaker of pregnancy, increasing the risk of preterm birth (Allen, 2001; Peterson et al., 2020) and thus impairing vagal development during the last weeks of gestation. In turn, the stretch-sensitive baroreceptors were activated, stimulating the cardioinhibitory center and causing rapid slowing of the heart rate mediated via the vagus nerve. Clark SL, Hamilton EF, Garite TJ, Timmins A, Warrick PA, Smith S. The limits of electronic fetal heart rate monitoring in the prevention of neonatal metabolic acidemia. In particular, several studies have shown how vagus nerve is involved in many vital processes during fetal, perinatal, and postnatal life: from the regulation of inflammation through the anti-inflammatory cholinergic pathway, which may affect the functioning of each organ, to the production of hormones involved in bioenergetic metabolism.

Maternal vitamin D status during pregnancy and child outcomes. Even in the sheep experiments using precisely controlled conditions, consistent fetal heart rate decelerations could not be produced equally in all animals despite 2 hours of repetitive maternal vascular occlusions.12 The late decelerations induced by constricting the sheep uterine arteries with and without acidemia are redrawn to scale on the grid used by fetal monitoring paper in Figure 4.

An increase in arterial blood pressure produces vessel distension and causes arterial baroreceptors to send neuronal messages to the cardioinhibitory center, which in turn causes rapid slowing of the fetal heart rate via the parasympathetic vagus nerve. doi: 10.1542/peds.2015-4271, Conradt, E., Crowell, S. E., and Lester, B. M. (2018). There are many observed effects of this medication on fHRV and fetal breathing patterns, mostly transient and dose-/time-dependent (van Geijn et al., 1980; Kariniemi and Mml, 1981; Low et al., 1981; Viscomi et al., 1990; Capogna, 2001; Mattingly et al., 2003; Shekhawat et al., 2020). Psychopharmacology (Berl.) As the vagus nerve affects the body metabolism in a pleiotropic manner, such a review could help better understand the networks underlying this effect and how to harness them for improving fetal and neonatal health (Castel et al., 2020).

However, the literature shows that the ANS can be assessed through fHRV from 15 to 20 WGA (Hoyer et al., 2012, 2013b, 2015, 2019; Shuffrey et al., 2019). JAMA. (2008). doi: 10.1038/s41390-021-01420-x. Gender does not affect fetal heart rate variation. Around the transition between the 1st and 2nd trimester, even the circumventricular organs, in particular, the area postrema, appear: they are organs devoid of the brain-blood barrier that, hence, allow the brain to be directed informed about the biochemical status of the internal milieu (Gokozan et al., 2016).

This is the reason why a measure of vagal modulation like RMSSD could help predict a similar event. 78, 17881798. Many postnatal pathologiese.g., hyperbilirubinemia, congenital heart disease, respiratory distress syndrome, respiratory syncytial virus, NEC, and sepsiscan lead to ANS impairment, probably due to inflammatory cytokines and toxins that can bypass the brain-blood barrier and induce neural death in areas paramount to ANS control (Fritze et al., 2014; Al-Shargabi et al., 2017; Bonaz et al., 2021).

The influence of betamethasone on fetal heart rate variability, obtained by non-invasive fetal electrocardiogram recordings. Arterial baroreceptors are sensitive to stretch or distension of a vessel caused by blood pressure changes. 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).

M., Mller, A., Zelgert, C., Shen, C., Su, P. C., Schmidt, G., et al. Fetal heart rate variability and cerebral oxygen consumption in fetal sheep during asphyxia. Exposure to acoustic stimuli, through vibroacoustic stimulation (VAS), is one of the most used benchmarks for the assessment of fetal distress, since VAS induces a somato-cardiac effect mediated by the fetal behavioral states (Busnel et al., 1992). In fetal surveillance, the situation is very different. doi: 10.1097/OGX.0000000000000007, Verdurmen, K. M. J., Warmerdam, G. J. J., Lempersz, C., Hulsenboom, A. D. J., Renckens, J., Dieleman, J.

A framework for standardized management of intrapartum fetal heart rate patterns.Am J Obstet Gynecol. J. Obstet. Recently, placenta calcifications samples collected at delivery have been speculated to act as a memory of prenatal maternal stress and diseases exposure, hence highlighting the potential role of placenta in regulating the offspring's future cardiovascular and metabolic health, even through the in utero modulation of the developing ANS (Wallingford et al., 2018).

As pathologies can affect ANS development, altered ANS function can make newborns more vulnerable to those same pathologies, due to failure in activating efficient anti-inflammatory reflexes including the CAP (Yiallourou et al., 2012; Mulkey et al., 2018; Bonaz et al., 2021).

The mechanisms of homeostatic intrinsic plasticity depend on the abundance and spatial distribution of voltage-gated ion channels (Na+,K+ and Ca2+ channels) at the plasma membrane, and on their biophysical characteristics. 28, 377382. Int. Comput. From 25 WGA until birth, the vagus nerve myelination, the vagal control by the nucleus ambiguus, and, thus, the PNS rapidly develop, as testified by the appearance of short-term variability in frequency-domain HRV metrics (e.g., HF) and the proportional reduction of long-term variability metrics (e.g., LF), more related to SNS and baroreflex functions (Mulkey and du Plessis, 2018, 2019; Schlatterer et al., 2021).
