The newborn's brain is distinguishing between mother's voice and other women's voices

University of MontrealAccording to the study of the newborn baby from birth immediately after birth to 24 hours after birth, when the newborn boy heard mother's voice and other women's voice, it turned out that the different part of the brain responded is. Mother's voice is to activate parts related to learning languages ​​in the newborn's brain.

Details are as below.Mom's voice plays special role in activating newborn's brain

Dr. Maryse Lassonde of University of Montreal and colleagues measured brain waves while sleeping in a newborn baby within 24 hours of birth and examined the response to the mother's voice and the voice of other women (nurses).


The neonatal mother and nurse gave a voice called "A" (short "a" like French "Arrow" instead of "A"), whereas in the mother's voice the left hemisphere of the newborn brain, Parts responsible for linguistic processing and exercise in particular responded, and it seems that the right hemisphere of the brain reacted in the voice of a nurse. The response of the right hemisphere is related to speech recognition.

In addition, the female nurses who participated in the experiment are mothers who have children as well, in order to exclude the possibility that the newborn may have heard it in the womb and the possibility that it distinguishes for the first time "unknown voice" heard, birth It seems that he was talking to the mother of the subject regularly before (regularly letting the fetus speak). In addition, he said he chose a nurse with a voice similar to his mother by voice analysis.

The woman who resembles only mother 's voice specially responds only to the voice of a mother, even a baby that many women grew in a multilingual environment that spoke a number of languages ​​also told mothers' words first Is it a mechanism to attach? The first language is "mother tongue" or "Mother tongue" may be a real expression.

It has long been known that babies already have some language ability from their birth. For example, a baby who heard the sound of "A" can be said to be a congenital knowledge such as opening a mouth in the form of "A" even if he never saw that sound by a person is. However, this field has not been elucidated yet, and this time scientifically supported that "mother's voice is special for newborn babies" is a big step toward elucidating the language ability of the newborn and the mechanism of language acquisition It is said that it will be.

"This study supports the fact that mothers are the first beings to convey languages ​​to newborns, suggesting that there is a neurobiological link between prenatal language acquisition and motor skills necessary for speech I am doing it, "Dr. Lassonde says.
