Relationships Between Central Auditory Function and Learning Disabilities
… identified learning problems on tests of central auditory function. Katz's Staggered.Spondaic Word (SSW) test and Willeford's Tests of Central Auditory Function (TCAF) were administered.</p> <p>The groups consisted of twenty-one LD children (experimental) and twenty-one children with no identified …

Using otoacoustic emissions to evaluate efferent auditory function in humans
<p>The auditory system continually adapts to changes in the acoustic environment over short periods of time. This fine-tuning of its dynamics is mediated in part by the medial olivocochlear (MOC) bundle, a neural feedback loop which aids in the regulation of cochlear micro-mechanics. The ability to …

A Comparative Analysis of Tests for Central Auditory Function and Tests for Auditory Processing
… between the results obtained from tests of auditory language performance and those obtained from tests of central auditory performance. The performances of ten learning disabled children were compared with the performances of ten normal achievers on the six auditory language subtests of the …

A profile of the auditory function of children with TB receiving ototoxic medication at Brooklyn Chest Hospital
… survey research design was used to describe the auditory function of children with tuberculosis (TB) receiving ototoxic medication at Brooklyn Chest Hospital. A battery of audiologic tests (otoscopy, immittance, audiometry or OAE and AABR) were conducted on 29 children, aged 0 to 18 years, and …

The Relationship Between Hospital Construction and High Risk Infant Auditory Function at NICU Discharge: A Retrospective Descriptive Cohort Study
<p>Purpose: To determine the difference in auditory function at NICU discharge between those high risk infant cases exposed to hospital construction during NICU stay and those not exposed.</p> <p>Background: Noise produced by routine NICU caregiving exceeds recommended intensity. As California …

Development of Cochlear Nonlinearities in Normal and Tshr Mutant Mice
… To accomplish these goals, the development of auditory function was studied in both normal mice (BALB/c) and a strain commonly referred to as the hyt, or Tshr mouse. The Tshr mouse expresses a naturally occurring point mutation in the gene that encodes the thyrotropin receptor resulting in the …

Vestibular Evoked Myogenic Potentials and Postural Control in Adults with Age-Related Hearing Loss
<p>It is well-documented that auditory thresholds decrease with age, which can be referred to as Age-related hearing loss (ARHL). ARHL is one of the most common conditions affecting older adults and is associated with several conditions including decreased postural stability and falls. Age-related …

Effects of Developmental Exposure to Environmental Contaminants on the Auditory System
… of neurotoxic effects, including long-term auditory deficits. We assessed auditory function in adult rats developmentally exposed to a unique PCB mixture formulated to model the congener profile of PCBs found in fish consumed by a human population in northeastern Wisconsin. Measurements of …

Characterization in cochlea of KCTD12/PFET1, an intronless gene with predominant fetal expression
… protein pfetin in relation to its role in auditory function. Experimental data from tissue and cellular expression profiling, and genetic and functional analyses suggests KCTD12 and its orthologs playing a crucial role in the developmental of the auditory sense organ.

Collecting Normative Data for Video Head Impulse Testing, Horizontal and Vertical Measures
A new test of vestibular function, video head impulse testing (vHIT), evaluates function of the anterior and posterior vertical semicircular canals as well as the horizontal canals. Our goal was to collect normative data for vHIT in both horizontal and vertical planes. Horizontal data was compared …

Tension Propagation Along Tip-Link Cadherins: Regulation and Implications for the Auditory System
… the full frequency and intensity range of auditory stimuli. In the present work, we model the tip link as a worm-like chain and evaluate its fast dynamic response using theoretical and numerical calculations. Our analysis uncovers frequencies at which the tip link exhibits viscoelastic …

Hearing Function in Obstructive Sleep Apnoea (OSA) patients and its impact with Continuous Positive Airway Pressure (CPAP)
… obstructive sleep apnoea (OSA) and hearing dysfunction has not been comprehensively evaluated. The obstruction of the upper airway in OSA could lead to anatomical changes to the eustachian tube, thus impacting middle ear function. In addition, the recurrent decrease in oxygen saturation during …

Mechanical Control of Sensory Hair-Bundle Function
<p>Hair bundles detect sound in the auditory system, head position and rotation in the vestibular system, and fluid flow in the lateral-line system. To do so, bundles respond to periodic, static, and hydrodynamic forces contingent upon the receptor organs in which they are situated. As the …

Multi-Modality Assessment Of Language Function
… a multi-modality study of language structure and function. The primary functional modality employed is task-related electrocorticography (ECoG). This is complemented by discussion and evaluation of previously published functional magnetic resonance imaging (fMRI) data. Language-related structure …

Otoacoustic emission (OAE)-based measurement of the functioning of the human cochlea and the efferent auditory system
… of cochlear mechanics and the efferent auditory system. OAE are sounds generated within<br/>normal cochlea either spontaneously or in response to stimulation. The ability to measure OAE non-invasively, objectively and quickly makes a powerful tool to probe cochlear mechanics. Stimulation …

Interactive effects of developmental PCB exposure and relevant environmental risks on the auditory system
… PCB exposure has been shown to cause auditory deficits that last through adulthood. We assessed the interaction of PCBs with other environmental risks to examine if there were additive or interactive effects on auditory function. Rats were exposed developmentally to a unique …
