Los autores, de la Universidad de Turku, midieron la actividad eléctrica en el cerebro de tres grupos de 15 recién nacidos (de uno a siete días de vida) cada uno. El primer grupo dormía mientras oía series de sonidos vocales repetidos de la lengua finlandesa, que en ocasiones variaban ligeramente. Estos cambios se asociaron a variaciones en la actividad eléctrica cerebral. A los del segundo grupo se les hizo oír otro tipo de sonidos, y el tercero fue el grupo control.
El estudio revela que los neonatos del primer grupo fueron capaces de distinguir los sonidos vocálicos mientras dormían, al contrario que los otros grupos.
