ABOVE: Infant and parent wearing EEG caps

When infants play with toys, their brains buzz with spurts of high-frequency activity accompanying their early attempts at paying attention. Using electroencephalography (EEG) researchers watched the brain activity of parents playing with them and found that the parents’ brain activity tracked that of the children’s attention patterns, researchers reported December 13 in PLOS Biology. The study suggests that a parent’s brain response echoes the child’s because when they’re playing together, the parent tracks where the child is looking.
