Babies who have a lullaby played to them regularly while still in the womb can recognize the song months after birth, a study has found.
The researchers had 10 expectant mothers play "Twinkle Twinkle Little Star" loudly multiple times per week throughout their last trimester of pregnancy. A few days after birth, they took electroencephalogram (EEG) recordings of each newborn's brain by using 12 electrodes scattered over different regions of the head.
Upon hearing the lullaby again, they had significantly larger brain responses than a control group of newborns who had not been exposed to the song.
