A study led by neuroscientist Peter Fransson of the Karolinska Institute in Sweden shows that there is spontaneous activity in at least 5 resting-state networks in the brains of sleeping babies.
Fransson and his colleagues used functional magnetic resonance imaging (fMRI) to scan the brains of 12 sleeping babies, for 10 minutes each. They found that there was activity in parts of the brain associated with the processing of visual, motor and auditory information.
This type of activity had previously been observed in sleeping adults, but until now it was unclear whether or not it also occurs in babies. The findings are published online in the Proceedings of the National Academy of Sciences.
