4D Scans Show Baby Yawning

Not only hiccups and kicks: the fetus in the belly of the mother yawns, and he does so often. Evidence of this are the results of a study published in PLoS ONE `'by researchers at Durham University, which could provide the key to a better understanding of the health of the unborn child. 4D scans of 15 healthy fetuses (which allow you to see in three dimensions the child but, unlike 3D ultrasound, they also offer moving images), conducted by researchers from Durham along with colleagues at the University of Lancaster (Gb) suggest that yawning is part of the process of child development, and may provide physicians with another index of the health of the fetus.
Some researchers have suggested that fetuses sbadigliassero, but according to other experts it was a simple movement of the mouth opening. Now new research has allowed us to clearly distinguish the yawn, and this according to its duration. The researchers used a 4D movie to closely examine what happens when a baby opens his mouth in the belly. Using newly developed criteria, the team found that more than half of the movements of mouth opening observed in the study are actually yawning. The work was conducted on eight females and seven males of 24-36 weeks of gestation. The researchers also found that yawning is reduced to from 28 weeks, with no difference between males and females in terms of frequency.
Although the role and significance of yawning are still unknown, the results of the study suggest that yawning may be linked to the development of the fetus, and therefore this action could provide a further medical indication on the health of the unborn child. "The results of this study - says Nadja Reissland the Department of Psychology at Durham University - show that yawning can be observed in healthy fetuses. Moreover, the frequency of yawning decreases with increasing age "of the unborn child. "Unlike us, the fetuses yawn because` infected '"by someone else," or because they sleep. The frequency of yawning in the womb may be linked to brain development in the early stages of gestation. Since the frequency of `yaown 'in our sample of healthy fetuses fell from 28 to 36 weeks of gestation, this seems to suggest a function of aging" due to its yawn. According to the researcher, in short, yawning in the belly could be linked to the maturation of the central nervous system of the child, but it is a theory that concludes the expert, should be examined with further research, which include mothers and babies.
