The brain mechanisms of hearing include large regions of the anterior temporal, prefrontal, and inferior parietal cortex, and an extensive network of descending connections between the cortex and sub-cortical components of what is presently known as the auditory system. One important function of these additional ("top-down") mechanisms for hearing…

The human auditory system is often portrayed as precocious in its development. In fact, many aspects of basic auditory processing appear to be adult-like by the middle of the first year of postnatal life. However, processes such as attention and sound source determination take much longer to develop. Immaturity of higher-level processes limits the…

In normal-hearing children the latency of the P1 component of the cortical evoked response to sound varies as a function of age and, thus, can be used as a biomarker for maturation of central auditory pathways. We assessed P1 latency in 245 congenitally deaf children fit with cochlear implants following various periods of auditory deprivation. If…

Thirty-six chronically hoarse children (mean age nine) with nodules were found to be similar to those without nodules on various perceptual measures. Twenty of thirty of these children showed improvements after a year of rehabilitation in the public schools; improvement varied according to the abilities of individual clinicians. (Author/CL)

A sequel to a report of acoustic characteristics of oral reading by 36 (aged 10-12 years), children, this article describes results: of perceptual analyses of oral reading proficiency on a five-point scale; of reading error analysis; and of multiple regression analysis for testing predictability of the oral reading proficiency from the perceptual…

This article discusses findings concerning the plasticity of auditory cortical processing mechanisms in adults, including the effects of restricted cochlear damage or behavioral training with acoustic stimuli on the frequency selectivity of auditory cortical neurons and evidence for analogous injury- and use-related plasticity in the adult human…

A bird study found that with sufficient time and training after hair cell and hearing loss and hair cell regeneration, the mature avian auditory system can accommodate input from a newly regenerated periphery sufficiently to allow for recognition of previously familiar vocalizations and the learning of new complex acoustic classifications.…
