Researchers from RIKEN Brain Science Institute shows that babies and mouse pups are likely to relax deeply when they are carried.

In the journal Current Biology, a study was published stating that they are the first one to demonstrate that infants coordinate sets of nervous, motor and cardiac regulations in response to calm themselves down. Researchers Kumi Kuroda, Gianluca Esposito and Sachine Yoshida proposed that it might be an evolutionarily conserved, and essential, component of mother-infant interaction.

At RIKEN, Kuroda and her colleagues determined that the calming process by the parasympathetic nervous system and also a region of the brain is called the cerebellum, it is also known as the little brain in Latin. According to researchers, the tactile inputs and proprioception are the reason why the calming response was dependent.

The ability to sense, understand body movements and keeping track of your body’s position is called proprioceptor. The reason why the nervous system helped lower the heart rate is called parasympathetic and is a part of mediating the coordinated response to being carried.

According to Dr Kuroda, a baby will become calm because when they were lifted up, and it is not specific to mothers only this calming effect can be to anyone including caregiver.

This is the first study that showed how the infant’s calming process was responded to being carried.

It is due to the coordination of the set of central, motor, and cardiac regulations that is an evolutionary preserved aspect of mother-infant interactions. This study also stated that this gives a scientific explanation for many new parents on why their babies often begin crying immediately when they put them down.

Such proper understanding of infants would reduce the frustration of parents and be beneficial because unsoothable crying is a major risk for child abuse,

said, Dr Kuroda.
