Mothers' and babies' brains can work together as a 'mega-network' by synchronizing brain waves when they interact. The level of connectivity of the brain waves varies according to the mom's emotional state: when mothers express more positive emotions their brain becomes much more strongly connected with their baby's brain. This may help the baby to learn and its brain to develop.

The research, published in the journal NeuroImage, used a method called dual electroencephalograhy (EEG) to look at brain signals in both moms and babies while they were interacting with each other. They found that moms and babies tend to synchronize their brain waves -- an effect known as interpersonal neural connectivity -- particularly in the frequency of 6-9 hertz, the infant alpha range.
