This article is republished with permission of Hearing Review   Research | May 2017 Hearing Review By Gail D. Chermak, PhD, Frank E. Musiek, PhD, and Jeffrey Weihing, PhD   There is general scientific agreement on the definition, diagnosis, and treatment of CAPD Central auditory processing disorder (CAPD) is a complex and evolving subject, but remains a solid diagnostic entity.

Frank Musiek     Introduction   Back in the 1950’s Ettore Bocca and his Italian colleagues (Bocca, Calearo, Cassinari, 1954) were the first to develop and make significant clinical use of central auditory tests. They had learned that the pure tone audiogram was not useful in reflecting deficits of the central auditory nervous system (CANS). They then proceeded to develop

Aaron Whiteley   The focused examination of otoacoustic emissions began in the 1940s with Georg von Bekesy. Inspired, yet unconvinced by Helmholtz’ idea that the cochlea consisted of resonant structures, Bekesy developed an intricate method of examination that would lead to the place theory and traveling wave theory (Hall, 2000). Bekesy’s experiments built the foundation for a common understanding that

Frank E. Musiek   There is no question that considerable research has been conducted on the cochlear nucleus in recent years. Anatomists, physiologists, psycho-acousticians, audiologists and others have made contributions to our understanding of the CNu. However, in reflection on some current research of the CNu I kept thinking about some very early research which was clinical in nature that

Elissa H. Kawamoto, B.S. Graduate Student, Department of Speech, Language and Hearing Science, University of Arizona   In order to develop strong diagnostic and clinical skills, one must have a deep understanding of the anatomy and physiology of the entire system related to ones field of study. Considerable attention must be directed towards understanding the region where vestibular schwannomas grow. This is

Herbert Jay Gould, Ph.D. School of Communication Sciences and Disorders, The University of Memphis   Compressed speech has been studied since the early 1950s (Garvey 1953) and has been suggested as a tool for the diagnosis of APD since at least 1977 (Beasley and Freeman 1977). The general consensus is that abnormal performance on compressed speech material reflects a deficit in

By Mike Webb   The goose is dead…or at least partially cooked.  I use this metaphor, of course, as the goose who laid the golden eggs: in our audiology context, the “hearing aid” goose.  I, for one, believe it may be a positive, pivotal moment for strengthening the field of audiology. A similar pivotal moment occurred in 1978 for audiology

By Frank Musiek, Ph.D.   The insula (meaning island and sometimes called the Island of Reil) is located medial to the temporal lobe. If one were to pull away the temporal lobe in a lateral manner, the insula would be observed behind it. It looks like another cortex and is situated of course, close to the temporal lobe – the

Several topics are covered and I thought it would be of interest to our Pathways/HHTM readership. – FM}     A detailed understanding of the central auditory nervous
