Newborns discriminate novel from harmonic sounds: A study using magnetoencephalography

Using magnetoencephalography in assessing auditory skills in infants and children

“…MMRs to changes in simple sound features like sound frequency have been recorded in infants (Huotilainen et al, 2003;Cheour et al, 2004;Sambeth et al, 2006). They seem to resemble those recorded with ERPs in similar conditions (Kushnerenko et al, 2002b), as do responses to changes in phonemes in infants (Pihko et al, 2004;Kujala et al, 2004a), and some groups have also presented source location estimates (Imada et al, 2006;Pang et al, 2003), pointing to a source in the temporal areas of the brain.…”

“…Some researchers have compared responses to deviants and to novel sounds and suggest that there may be a contribution of the attentionallocation-related components like P3a or P300 to the response (Kushnerenko et al, 2002b(Kushnerenko et al, , 2007Sambeth et al, 2006). In infancy, disentangling the pre-attentive and attentive components of the response has not yet been done and remains a challenge in the field.…”

“…Some individual neonates have very large P3a responses to novel sounds (Sambeth et al, 2006). It would be important to study the development of such children, since large P3a responses in schoolaged children are typical in children who have problems in regulating their attention (Gumenyuk et al, 2001).…”

Effects of Recurrent Acute Otitis Media on Cortical Speech-Sound Processing in 2-Year Old Children

“…Noninvasive brain research techniques were shown to be eligible for studying objectively neural processing from early infancy and even during the fetal period (Sambeth et al 2006, e76 HAAPALA ET AL. / EAR & HEARING, VOL.…”

Effect of maturation on suprasegmental speech processing in full- and preterm infants: A mismatch negativity study

“…The MMN paradigm is seen as ideal for infant studies as it measures pre-attentive change detection mechanisms, present even in newborns, and are sensitive to various kinds of deviances (cf. Ceponiene et al (2002); Dehaene-Lambertz and Baillet (1998); Kujala et al (2004); Kushnerenko, Ceponiene, Balan, Fellman, and Näätänen (2002); Pihko et al (1999); Sambeth, Huotilainen, Kushnerenko, Fellman, and Pihko (2006). Most of the MMN studies focusing on prosodic information use a single feature, mostly the duration of sounds.…”
