How Can You Keep the Baby Stay Longer in Womb
Babies Create a Mental Map of Their Body Before They Ever Leave the Womb
Among the most exciting moments during pregnancy is when a female parent-to-be feels her baby move inside her. Now, research suggests that that kicking isn't just for kicks: With each kick and jab, your infant may be mapping out its brain and edifice an data superhighway.
These kicks, known as fetal movements, enable a baby to construct a basic encephalon network so that it can understand what part of the body is moving and how it is being touched, the researchers found.
This early spatial mapping lasts just until birth, when within just a few days, the very same types of movements no longer accept the aforementioned outcome on the encephalon. It is as if the movements in the womb are preparing the baby for life on the outside, providing the neural scaffolding upon which the brain volition build layers of complexity with all the new kinds of sensory input in the globe, the researchers suggested.

And the reward for feeling around inside the womb is nearly instant.
"These key aspects of impact are useful immediately from birth for skills like breastfeeding," said Kimberley Whitehead, a doctoral student at University College London (UCL), who co-led the study.
The study's findings may have implications for neonatal clinical care, such as how to wrap a very premature baby so that information technology tin can maintain that sense of being in the womb and further develop this basic brain network, said Whitehead and her dissertation adviser and study co-lead, Lorenzo Fabrizi, a senior research fellow at UCL.
The report is published today (Nov. 30) in the journal Scientific Reports.
Previous research conducted by others has plant that spontaneous movements and consequent feedback seen simply subsequently birth are necessary for proper brain mapping in animals such as rats. Even so rodents are born in a premature state, less developed than newborn humans. For example, baby rats don't open their optics until they are about 13 days old.
The question for Fabrizi was whether humans have the aforementioned early on encephalon mapping before nativity. And yet, researchers tin can't written report the brain waves of babies yet in the womb. [That's Incredible! ix Brainy Baby Abilities]
And so, Fabrizi's laboratory devised a study in collaboration with University College London Hospital to examine a diverseness of newborn humans, including those built-in premature. A total of 19 newborns, about 2 days sometime, on average, took part in the study; they were between 31 and 42 weeks in so-called corrected gestational age when studied. Corrected gestational historic period takes into account their historic period if they were still in the womb; a babe built-in at 35 weeks and existence 1 week onetime, for instance, would have a corrected gestational age of 36 weeks.
Using noninvasive electroencephalography (EEG), the researchers measured brainwaves as these infants slept, focusing on the times when the newborns kicked their limbs during rapid centre move (REM) sleep. And they found evidence for this building of brain networks, especially amongst the prematurely born babies.
For example, the movement of a baby's right hand caused brain waves to burn down immediately afterward in the part of the left brain hemisphere that processes touch for the correct paw. The size of these brain waves was larger (meaning a greater increase in activity) in premature babies, who at their age would otherwise still exist in the womb, compared with the infants born total-term.
Whitehead said her team's most contempo data, not yet published, suggests that other aspects of touch develop in the first several weeks after birth, such as combining information from both the left side and the right side of the body.
"These early patterns [developed in utero] lay out the pathways on which so experience later birth tin piece of work on to refine the initial map," Whitehead told Live Scientific discipline.
For premature babies, the findings propose that keeping a newborn swaddled or nested in a cot may exist benign to allow the baby to feel a womb-like surface when he or she moves. Likewise, every bit these movements were observed during REM slumber, the results support the notion that slumber should exist protected in newborns in hospitals with minimal disturbance for necessary medical procedures.
They are busy building their beautiful brains, later all.
