A mother's voice preferentially activates language acquisition areas of their newborn infant's brain...

While the actuality is a "Duh!", it is fascinating to me on two counts.

First when analyzing brain activity, smaller functional components are being identified.

Second is the picture copied below.  The sacrifices we go through for science.  Informed consent?  Say what?

Language Learning areas of Baby's Brains are activated by their mother's voice.

For preemies, or sick babies, or for those whose mother's die in childbirth, one wonders if a tape loop of the mother's voice is enough to produce an equivalent effect.
