“…Developmental science has most often relied on studies comparing fraternal and identical twins to parse the genetic contribution to behavior. Although there are a few studies of fetal behavior in twins, most consider chorionicity over zygosity (Gallagher, Costigan, & Johnson, 1992; Tendais, Visser, Figueiredo, Montenegro, & Mulder, 2013). Moreover, twinning is an anomalous condition of human pregnancy and it cannot be presumed that the intrauterine milieu for both fetuses is the same.…”

Among the earliest volumes of this Monograph series was a report by Lester Sontag and colleagues, of the esteemed Fels Institute, on the heart rate of the human fetus as an expression of the developing nervous system. Here, some 75 years later, we commemorate this work and provide historical and contemporary context on knowledge regarding fetal development, as well as results from our own research. These are based on synchronized monitoring of maternal and fetal parameters assessed between 24 and 36 weeks gestation on 740 maternal-fetal pairs compiled from eight separate longitudinal studies, which commenced in the early 1990s. Data include maternal heart rate, respiratory sinus arrhythmia, and electrodermal activity and fetal heart rate, motor activity, and their integration. Hierarchical linear modeling of developmental trajectories reveals that the fetus develops in predictable ways consistent with advancing parasympathetic regulation. Findings also include: within-fetus stability (i.e., preservation of rank ordering over time) for heart rate, motor, and coupling measures; a transitional period of decelerating development near 30 weeks gestation; sex differences in fetal heart rate measures but not in most fetal motor activity measures; modest correspondence in fetal neurodevelopment among siblings as compared to unrelated fetuses; and deviations from normative fetal development in fetuses affected by intrauterine growth restriction and other conditions. Maternal parameters also change during this period of gestation and there is evidence that fetal sex and individual variation in fetal neurobehavior influence maternal physiological processes and the local intrauterine context. Results are discussed within the framework of neuromaturation, the emergence of individual differences, and the bidirectional nature of the maternal-fetal relationship. We pose a number of open questions for future research. Although the human fetus remains just out of reach, new technologies portend an era of accelerated discovery of the earliest period of development.

“…Abnormal heart rate patterns are suggestive of foetal distress (13). Although it is well recognised that FHR decreases during the course of pregnancy in farm animals (3,11,(14)(15)(16) except in goats (16), there are no data available on the FHR curve through singleton and multiple pregnancies in domestic animals.…”

“…The longitudinal assessment of fetal movements is a major strength of this study. However, several limitations need to be recognized, namely the relatively small sample size, but still larger than in most other studies (Tendais, Visser, Figueiredo, Montenegro, & Mulder, ). Other limitations include lack of simultaneous observation of both twins’ fetal movements in a third of the recordings, the inability to control for possible confounders like diurnal rhythms and prandial effects.…”

This study examined the developmental trajectories of general and breathing movements in fetal twins. Fetal movement patterns were assessed from real‐time ultrasound recordings performed at 12‐15, 20‐23, and 28‐32 weeks of gestation in 42 twin pairs. Results indicated that both general movements and breathing movements followed a curvilinear, inverted U‐shaped curve. Developmental trajectories were unrelated within pairs of twins and were not associated with gestational age at birth and birth weight. However, sex differences were found for general movements with males displaying more time making general movements at 21 weeks and a steeper decline in time spent making general movements during the second half of pregnancy than females. These age‐related changes in fetal movements may reflect CNS development. These findings also suggest that twins’ behavioral development is largely independent of co‐twin development, gestational age at birth, and birth weight, but not of fetal sex.
