  • Central Auditory mechanisms associated with cochlear implantation: an overview of selected studies and comment.
    Cochlear Implants International, 2010
    Co-Authors: Frank E Musiek, Shannon B Daniels
    Abstract:

    Recently, the evaluation of the role of the central Auditory System in the utilization of cochlear implants has received much attention. In order to fully understand the results of cochlear implantation, one must have an understanding of how the brain is influenced by electrical stimulation of the Auditory nerve. This review provides an overview of the structure and function of the central Auditory Nervous System and the changes that occur as a result of cochlear implant use. Evidence of central Auditory plasticity is discussed highlighting key imaging and evoked potential studies.

  • The Auditory steady state response in individuals with neurological insult of the central Auditory Nervous System.
    Journal of the American Academy of Audiology, 2007
    Co-Authors: Jennifer B. Shinn, Frank E Musiek
    Abstract:

    The Auditory steady state response (ASSR) has recently gained attention with respect to estimates of hearing sensitivity and configuration of hearing loss. The present investigation compared behavioral thresholds to estimated ASSR thresholds in subjects with confirmed CANS lesions to determine if this population can be accurately evaluated with ASSR techniques. Comparisons were made between the experimental group and a normal control group matched for age and hearing sensitivity. ASSR thresholds were obtained for the carrier frequencies of 500 and 2000 Hz with a 46 Hz modulation rate and compared to behavioral thresholds. Within and between group comparisons were made. The control group demonstrated strong correlation between their behavioral and estimated ASSR thresholds which significantly contrasted the neurological group. Additionally, individuals with neurological impairment of the CANS exhibited elevated thresholds that were on average 24 dB greater at 2000 Hz than their behavioral thresholds. These results suggest that individuals with neurological insult may appear as hearing impaired or having greater hearing loss than is actually present. As a result, the ASSR may demonstrate the potential to assist in the detection of CANS dysfunction.

  • Nonmodularity of the central Auditory Nervous System: implications for (central) Auditory processing disorder.
    American journal of audiology, 2005
    Co-Authors: Frank E Musiek, Teri James Bellis, Gail D Chermak
    Abstract:

    This response to A. T. Cacace and D. J. McFarland (2005) identifies points of agreement and disagreement regarding the concept of modularity in the diagnosis of (central) Auditory processing disord...

  • Differential diagnosis and management of central Auditory processing disorder and attention deficit hyperactivity disorder.
    Journal of the American Academy of Audiology, 1999
    Co-Authors: Gail D Chermak, J W Hall, Frank E Musiek
    Abstract:

    Children diagnosed with attention deficit hyperactivity disorder (ADHD) frequently present difficulties performing tasks that challenge the central Auditory Nervous System. The relationship between ADHD and central Auditory processing disorder (CAPD) is examined from the perspectives of cognitive neuroscience, audiology, and neuropsychology. The accumulating evidence provides a basis for the overlapping clinical profiles yet differentiates CAPD and ADHD as clinically distinct entities. Common and distinctive management strategies are outlined.

  • Central Auditory tests.
    Scandinavian audiology. Supplementum, 1999
    Co-Authors: Frank E Musiek
    Abstract:

    This article overviews some selected central Auditory test procedures as well as some popular issues that surround them. Both behavioral and electrophysiologic central Auditory tests are discussed in reference to their clinical value as judged by their sensitivity, specificity, administration time, and reliability. Also discussed are diagnostic trends that are noted on behavioral and electrophysiologic procedures. Relationships are drawn between children with Auditory processing deficits associated with learning problems and individuals with neurological lesions of the central Auditory Nervous System.

  • Hearing aids for the treatment of tinnitus.
    Progress in brain research, 2007
    Co-Authors: L. Del Bo, U. Ambrosetti
    Abstract:

    Clinical evidence shows that the use of hearing aids in tinnitus patients provides two benefits: it makes the patient less aware of the tinnitus and it improves communication by reducing the annoying sensation that sounds and voices are masked by the tinnitus. Hearing loss reduces stimulation from external sounds resulting in increased awareness of tinnitus and deprivation of input may change the function of structures of the Auditory pathways. Tinnitus is often caused by expression of neural plasticity evoked by deprivation of Auditory input. With hearing aid amplification, external sounds can provide sufficient activation of the Auditory Nervous System to reduce the tinnitus perception and it may elicit expression of neural plasticity that can reprogram the Auditory Nervous System and thereby have a long-term beneficial effect on tinnitus by restoring neural function. To obtain the best results, hearing aids should be fitted to both ears, use an open ear aid with the widest amplification band, and disabled noise reducing controls. In some cases a combination device would be preferable. The conditions required in order to obtain good results include not only the use of devices, but above all, their adaptation to the needs of the single patient, by counseling and customization. Wearing the hearing aid must become second nature to the patient even though it is only one element of the therapy.

  • GIN (Gaps-In-Noise) test performance in subjects with confirmed central Auditory Nervous System involvement
    EAR HEARING, 2005
    Co-Authors: E Zaidan
    Abstract:

    Objective: The purpose of the present study was to investigate the value of a new gap detection procedure called Gaps-In-Noise (GIN) for assessment of temporal resolution in a clinical population.Design: The test consists of 0 to 3 silent intervals ranging from 2 to 20 msec embedded in 6-sec segments of white noise. The location, number, and duration of the gaps per noise segment vary throughout the test for a total of 60 gaps presented in each of four lists. The GIN procedure was administered to 50 normal-hearing listeners (group 1) and 18 subjects with confirmed neurological involvement of the central Auditory Nervous System (group II).Results: Results showed mean approximated gap detection thresholds of 4.8 msec for the left ear and 4.9 msec for the right ear for group I. In comparison, results for group 11 demonstrated a statistically significant increase in gap detection thresholds, with approximated thresholds of 7.8 msec and 8.5 msec being noted for the left and right ears, respectively. Significant mean differences were also observed in the overall performance scores (i.e., the identification of the presence of the gaps within the noise segments) of the two groups of subjects. Finally, psychometric functions, although similar for short and long duration gaps, were highly different for gaps in the 4- to 10-msec range for the two groups.Conclusions: A variety of psychoacoustic procedures are available to assess temporal resolution; however, the clinical use of these procedures is minimal at best. Results of the present study show that the GIN test holds promise as a clinically useful tool in the assessment of temporal resolution in the clinical arena.
