Baby Crying and Laughing Learning since The Womb

Baby Crying and Laughing Learning since The Womb
Apparently the baby has learned to cry and laugh from inside the uterus. This conclusion is known from studies of a group of researchers who studied the development of babies in the womb. Research shows that babies' facial expressions evolved from 24-36 weeks gestation. After that, the baby's expressions and movements become more complex.

Growth of the fetus in the womb is a complex and fascinating man. Until then do not be surprised if a lot of people curious. The study, conducted this first mention babies have learned to convey the expression of happy and sad since there was in his mother's womb.

Baby in the womb menununjukkan various facial expressions and facial movements are likely an expression of crying and laughing. The study, published by Female First video recorded with fetal facial movements through 4D ultrasound mesih. Fetal development was monitored at weeks 20, 24 and 36. From time to time, the motion of the baby's face increasingly complex.

The first stage, the observations week 24, the fetus is capable of moving a facial muscle. The fetus is able to stretch the lips and open their mouths. At week 35, to weigh been able to combine a number of facial muscle movement. They've been able to stretch the lips, brows lowered, deepening of the nasolabial groove until the easily recognizable as an expression.

"The results of this study is an exciting new insights in the growth of the fetus in the womb. It was the first to show how complex the development of healthy babies have on the movement of his face, "said Brian Francis, professor of social statistics from the Faculty of Mathematics and Statistics, University of Lancaster.

However, the fetus is still not silent. The fetus is only to express themselves through facial movements, the expression of crying and laughing.

In the previous studies, infants known to be flashing before birth, and is known to pout when still in the womb. "This study is also the first time to develop a method of coding and analysis track gerakakn increasing complexity of the fetal face," added Dr Nadja Reissland from the University of Durham.

The researchers argue that these movements develop before a baby can feel the emotion, no such difference between breathing movements in utero.

The research team is eager to re-check to see whether the fetus can distinguish and respond to his mother that smokers and nonsmokers. As well as to examine developments related to the movement of facial expression that refers to the angry, and sad smile.
