The fetus has short-term memory at 30 weeks of age

According to the July 22 " Dakungpao " Hong Kong, perhaps everyone could not remember the days still in the womb, but in a recent study by Dutch scholars, the fetus is 30 weeks of age may have short-term memory .

Previously, everyone said the fetus was just a part. Although research projects over the past two or thirty years have gradually discovered your baby's neurodevelopmental condition before birth, researchers can't know when memory begins to form and How long can it be maintained?

Recently, in a research project, the fetus experiment of nearly 100 women reacted when there was stimulation. In the results of the researchers' experiments, this kind of stimulation is " stimulating barometric vibration, " which is a very small sound, but will create vibrations. Researchers adopted supersonic waves to observe fetal reactions. When the fetus receives stimulation for the first time, it will react. But after going through similar tests (13s / time), the fetus gradually got used to that sound, and there was no reaction.

Nijhuis - The obstetrician of the Maastricht University Medical Center Netherlands said: " A normal fetus is between 30, 32 or 34 weeks old, after 13 or 14 stimuli it will not respond. application ".

With repetitive stimuli, the reaction becomes smaller, called " habit " . This is an experience in humans and animals. For example, you might get used to the sounds coming from the heater at night, which is when you first hear that noise, but after a while you'll get used to it, and continue to fall asleep. sleep.

Dr Nijhuis said: " Habits are a form of learning and memory ." He and his colleagues took advantage of the routine experiment to conduct fetal memory experiments from 30 to 38 weeks of age. They discovered that a 30-week-old fetus has memory for about 10 minutes. Meanwhile, the 34-week-old fetus can store the information and can still recall it after 4 weeks.
