ImpactModerate impact

The discussions highlight the potential impact of these findings on understanding prenatal development and emotional bonding, though some users question the ethical implications.

Abstract in brief

  • Early exposure to maternal sounds like voice and heartbeat can influence brain development in premature infants, specifically increasing the size of the auditory cortex.
  • The study found that infants who listened to maternal sounds had a larger auditory cortex compared to those exposed only to hospital noise, indicating early brain adaptability based on sensory experience.
  • These findings suggest that even before full-term, the infant brain is sensitive to maternal sounds, which may impact future hearing and language development, highlighting the importance of early auditory experiences.]

@BraddockBessie The baby knew and heard their mother's voice already in the womb, the baby is missing their mother! "Newborns can hear their mother’s voice and heartbeat sounds before birth."

The Mother's death is a terrible tragedy. An unborn baby usually hears its Mother. This baby cannot. I had, by chance, recently read the following article

@EdmundSmirk There’s something cruel about growing a baby with the intent of taking it away from mom; that bond is physiologically important. Of course it can’t be helped in some situations, but why do this on purpose? Just adopt. https://t.co/4at91IXdKg

That fetuses hear, respond to and even learn from sound is well supported by evidence.
