Experience-dependent plasticity in pitch encoding: from brainstem to auditory cortex.
Linguistic and musical pitch provide an analytic window to evaluate how neural representations of important pitch attributes of a sound undergo transformation from early sensory to later cognitive stages of processing in the human brain, and how pitch-relevant experience shapes these representations. These pitch attributes are shaped differentially depending on their functional relevance to a l...
متن کاملContext-dependent plasticity in the subcortical encoding of linguistic pitch patterns.
We examined the mechanics of online experience-dependent auditory plasticity by assessing the influence of prior context on the frequency-following responses (FFRs), which reflect phase-locked responses from neural ensembles within the subcortical auditory system. FFRs were elicited to a Cantonese falling lexical pitch pattern from 24 native speakers of Cantonese in a variable context, wherein ...
متن کاملEffect of Norepinephrine depletion on induction of experience dependent plasticity in male rat barrel cortex
Introduction: Barrel cortex of rats is a part of somatosensory cortex, which receives information from facial whiskers. Vibrisectomy by sensory deprivation leads to some changes in the barrel cortex, which have been known as experience dependent plasticity. On the other hand, Norepinephrine (NE) and locus coeruleus, which is the main source of NE, influenced response properties of cortical bar...
متن کاملLanguage experience dependent plasticity for pitch representation in the human brainstem
Brainstem frequencies following responses (FFR) were recorded from Chinese and English participants in response to Mandarin tonal patterns presented in a speech and a nonspeech context. Results showed that the Chinese group exhibits stronger pitch representation and smoother pitch tracking than the English group. Moreover, the Chinese group exhibited relatively more robust pitch representation ...
متن کاملExperience-dependent neural plasticity is sensitive to shape of pitch contours.
Language experience is known to modulate the preattentive processing of linguistically relevant pitch contours when presented in the speech domain. To assess if experience-dependent effects are specific to speech, we evaluated the mismatch negativity response to nonspeech homologs (iterated rippled noise) of such curvilinear pitch contours (Mandarin: Tone 1, 'high level'; Tone 2, 'high rising')...
