Feel drear for mothers . Not only is the price of have a child simplyextortionate , but the human pelvis is not peculiarly well - adapted for the actual process of giving birth to large - lead newborns .
One of the ways humans have germinate to get around this narrow - pelvis , openhanded - school principal quandary is with a soft , plastic skull that primer and hardens at some level between seven and 18 months . This squishy skull can shapeshift under insistency , allow it to press through the giving birth epithelial duct .
Now , scientist have used 3D scanning to demonstratehowthe foetal brain changes condition during the pitch physical process . The results have been put out in the journalPLOS ONE .
Twenty - seven pregnant women were scanned with an MRI machine between 36 and 39 weeks of gestation period . Seven of these adult female were then scanned again , no more than 10 minutes before give birth .
The resulting images show varying degree of what they call " foetal read/write head moulding " , reveal readable differences between the first and second set of images . While not one of the 27 image in the first set show overlap foetal structures , all seven in the 2d set did – demonstrate the way the brain configuration change during labor to fit through the nascency epithelial duct .
Right after nativity , this " cranial misshapenness " was no longer seeable in five out of the seven baby . The parameters of their skull were " identical " to what they had been when in the womb .
As for the three newborns with the most detectable molding of the skull ( and the most severe mental capacity frame deformations ) , two were born by atomic number 6 - section and one was deliver via natural birth .
In 2017,photographer Kayla Reedercaptured some incredible images of a babe Graham , whose sideways placement resulted in uttermost molding of the skull . But do n’t worry – in this example , the child ’s head formed back into a normal flesh , highlight just how complex ( and flexile ) the human body really is .
