by  Frank E. Musiek, Ph.D.   Most audiologists are familiar with at least two major pathways in the brain. One is the ascending (and descending) auditory brainstem pathway and the other is the ascending (and descending) vestibular brainstem pathway. In the cerebrum there are also pathways of importance to audiology. These include, in our view, the superior longitudinal fasciculus (SLF),

Carrie M. Clancy, B.A., M.M. Graduate Student, Department of Speech, Language and Hearing Sciences, University of Arizona   Part 1 of this article provided a brief overview of congenital and acquired amusia as forms of CAPD. Part 2, presented here, is intended to suggest potential avenues for continued research regarding both congenital and acquired amusias.   Congenital Amusia Subtypes of

Carrie M. Clancy, B.A., M.M. Graduate Student, Department of Speech, Language and Hearing Sciences, University of Arizona   Commonly called “tone deafness”, amusia is defined as the inability to recognize or reproduce musical tones. Amusia can be congenital (present at birth) or acquired sometime later in life, as from brain damage due to stroke or injury. General symptoms of amusia

By: Frank Musiek The dichotic difference score (DDS) has been utilized periodically over the history of dichotic listening. It represents an interesting manipulation of dichotics and relates to its various applications. The DDS simply requires the computation of the differences on performance of dichotic listening between the right and left ears. Generally, this means that if the right ear score

by Frank E. Musiek, PhD A popular discussion for some time has been why can’t children under 7 years of age be tested for CAPD? Many audiologists and speech pathologists argue that much could be done for these children if only a diagnosis of CAPD could be rendered at an earlier age. This is certainly a worthy concept with which

Acquired hearing loss can negatively affect mental health, participation in interpersonal relations, and health-related quality of life. Population-based

[A preview of a the presentation at Pathways for AAA by Deborah Moncrief] Amblyaudia is a deficit in binaural integration, a process that begins with excitatory and inhibitory activation in the medial and lateral superior olivary complexes of the auditory brainstem (Tollin, 2003).  Interaural timing and intensity differences are used to detect coincident signals and to prioritize neural codes for

by Julianne M. Ceruti, Au.D., Ph.D., Leslie Bernstein, Ph.D., and Frank Musiek, Ph.D.   The Decrement in Noise Test (DeNT) is a clinically oriented procedure modeled after the GIN test that employs both partially filled gaps (i.e., decrements) and full gaps. This test was developed to improve clinical assessment of temporal resolution that addresses the intensity resolution confound when only

by Frank E. Musiek   Introduction The internal auditory meatus (IAM) is a canal in the temporal bone that extends from the bony cochlea medially to an opening in the posterior aspect of the petrous portion of the temporal bone. This structure is germane to audiologists because it contains three nerves of interest to audiologists: 1- the auditory nerve, 2-
