For some time there have been suggestions that previous termbabies next term in the womb hear outside sounds. New research shows that unborn previous termbabiesnext term not only hear previous termmusicnext term but also recognize it a year later. The research by Alexandra Lamont from the University of Leicester was presented in a BBC television documentary. Lamont exposed previous termbabiesnext term to a single piece of reggae, pop, classical or ‘world’ previous termmusicnext term for 30 minutes a day for the final three months before birth. A year after birth she tested the previous termbabies’ musicnext term preferences. When the previous termbabiesnext term looked away from the speakers the previous termmusicnext term was turned off, so a long time spent looking at the speakers was taken as evidence for preference. previous termBabiesnext term showed strong preferences for the piece of previous termmusicnext term they had heard in the womb, even though they had not heard it again between birth and the testing session. This shows that previous termbabiesnext term are able to remember things for much longer than previously thought. Lamont plans to follow up the group of previous termbabiesnext term to see whether the recognition is maintained, and whether the early exposure will affect the previous termbabiesnext term’ musical tastes later in life.

Language or music,next term mother or Mozart? Structural and environmental influences on infants’ language networks
G. Dehaene-Lambertza, b, c, d, Corresponding Author Contact Information, E-mail The Corresponding Author, A. Montavonta, b, d, A. Joberta, b, d, L. Allirold, e, J. Duboisd, e, L. Hertz-Pannierb, d, e, f, g and S. Dehaenea, b, d, h
Abstract
Understanding how language emerged in our species calls for a detailed investigation of the initial specialization of the human brain for speech processing. Our earlier research demonstrated that an adult-like left-lateralized network of perisylvian areas is already active when infants listen to sentences in their native language, but did not address the issue of the specialization of this network for speech processing. Here we used fMRI to study the organization of brain activity in two-month-old infants when listening to speech or to previous termmusic.next term We also explored how infants react to their mother’s voice relative to an unknown voice. The results indicate that the well-known structural asymmetry already present in the infants’ posterior temporal areas has a functional counterpart: there is a left-hemisphere advantage for speech relative to previous termmusicnext term at the level of the planum temporale. The posterior temporal regions are thus differently sensitive to the auditory environment very early on, channelling speech inputs preferentially to the left side. Furthermore, when listening to the mother’s voice, activation was modulated in several areas, including areas involved in emotional processing (amygdala, orbito-frontal cortex), but also, crucially, a large extent of the left posterior temporal lobe, suggesting that the mother’s voice plays a special role in the early shaping of posterior language areas. Both results underscore the joint contributions of genetic constraints and environmental inputs in the fast emergence of an efficient cortical network for language processing in humans.

For some time there have been suggestions that babies in the womb hear outside sounds. New research shows that unborn babies not only hear music but also recognize it a year later.

Babies showed strong preferences for the piece of music they had heard in the womb, even though they had not heard it again between birth and the testing session. This shows that babies are able to remember things for much longer than previously thought. Lamont plans to follow up the group of babies to see whether the recognition is maintained, and whether the early exposure will affect the babies’ musical tastes later in life.
