Baby can still hear in sleep

Talking and singing to your baby during sleep is not meaningless. Scientists have recently discovered that when babies sleep, the areas of the brain for hearing, vision and movement are still " awake ".

Recent studies have found evidence that in adults, 10 networks associated with resting states, including bundles of neurons, continue to function even though the person is sleeping. However, whether that is true for newborn babies is still a mystery.

"Recent research shows that there is activity in the infant's brain , " said team member Hugo Lagercrantz from Astrid Lindgren Children's Hospital in Sweden.

Lagercrantz and colleagues photographed the brain of 12 sleeping babies for 10 minutes, using functional magnetic resonance techniques. They found 5 networks related to the state of resting spontaneously. Just like in adults, these brain regions are associated with visual, auditory and motor processes.

What does this mean for young mothers?

"It confirms the notion that talking and singing to children while they sleep is not useless, but very good for them," Lagercrantz said.

For neuroscientists, the discovery opens up the light of human brain development, because the number of networks in the infant's brain is much less than that of adults.

"Perhaps these networks have grown gradually , " the authors said.
