Theta brain rhythms index perceptual narrowing in infant speech
Alexis Bosseler,Samu Taulu,Elina Pihko,Jyrki P. Mäkelä,Toshiaki Imada,Antti Ahonen,Patricia K. Kuhl +6 more
TL;DR: Theta brain oscillatory activity may provide an index of perceptual narrowing beyond speech, and would offer a test of whether the early speech learning process is governed by domain-general or domain-specific processes.
Journal ArticleDOI
Somatic evoked high-frequency magnetic oscillations reflect activity of inhibitory interneurons in the human somatosensory cortex
TL;DR: It is speculated that the high-frequency oscillations represent a localized activity of the GABAergic inhibitory interneurons of layer 4, which have been shown in animal experiments to respond monosynaptically to thalamo-cortical input with a high- frequencies burst of short duration spikes.
Journal ArticleDOI
Infant speech perception activates Broca's area : a developmental magnetoencephalography study
Toshiaki Imada,Yang Zhang,Marie Cheour,Marie Cheour,Samu Taulu,Antti Ahonen,Patricia K. Kuhl +6 more
TL;DR: The activation patterns observed in the superior temporal and inferior frontal regions provide initial evidence for the developmental emergence early in life of a perceptual–motor link for speech perception that may depend on experience.
Journal ArticleDOI
Infants' brain responses to speech suggest analysis by synthesis.
TL;DR: The findings have implications for: (i) perception-action theories of speech perception, (ii) the impact of “motherese” on early language learning, and (iii) the “social-gating” hypothesis and humans’ development of social understanding.
Journal ArticleDOI
Effects of language experience: Neural commitment to language-specific auditory patterns
Yang Zhang,Patricia K. Kuhl,Toshiaki Imada,Toshiaki Imada,Makoto Kotani,Yoh'ichi Tohkura,Yoh'ichi Tohkura +6 more
TL;DR: It is argued that early exposure to a particular language produces a "neural commitment" to the acoustic properties of that language and that this neural commitment interferes with foreign language processing, making it less efficient.
