Mother’s voice is Important to Activate Babies’ Brain
This was revealed from the result of a research conducted by researchers from the University of Montreal and Sainte-Justine University Hospital Research Centre.
To investigate this, the research team made the discovery after making electrical recordings in the brains of infants within 24 hours of birth. As a result, the brain signals revealed that while babies do not react to another woman’s voice, the voice of their mother will activate parts of the brain associated with language skills.
“This is an interesting study that proves for the first time that the infant’s brain responds strongly to their mother’s voice. This can be demonstrated scientifically,” said principal investigator Dr. Maryse Lassonde from the University of Montreal, according to ScienceDaily.
Dr. Lassonde explains, to conduct this research his team applied an electrode at 16 baby’s head while they were sleeping. Then the researchers asked each child’s mother to make a short vowel sounds, such as ‘Hello’ or ‘hi’.
“When they hear their mother’s voice, brain scans clearly show reaction in the left hemisphere, particularly in the section responsible for language and motor skills. This proves that ‘motherese’ that describe specific communication between infants and mothers, can be proven scientificly, “explained Dr Lassonde further.
It is known that babies have innate language ability, but with this study researchers begin to understand what the capacity is and how it works scientifically.
“This study confirms that women are the main initiators and shows that there is a neurobiological relationship between prenatal mastery of language and motor skills involved in how to talk,” said Dr. Lassonde.
The study is published in Cerebral Cortex and received funding from the Natural Sciences and Engineering Research Council of Canada, Canada Foundation for Innovation and Canada Research Chairs program.
