The symposium was planned to commemorate my new departure from the Univer- sity of Tokyo to the National Institute of Sensory Organs. Guest speakers from the United States, Australia, Korea, and Japan presented papers that focused on history, gene, pathophysiology, analysis, perception, sound localization, cochlear implants, and balance for auditory and vestibular neuropathy, with up-to-date information and knowledge. Altogether, there were many important presentations about this new disease, which was fi rst reported by Kaga K et al and Starr A et al in 1996. There are many unsolved issues such as gene location, site of pathology, and the effect of cochlear implants. In the last 10 years, hearing screening of newborns has been introduced in many countries, and auditory neuropathy is paid much more attention because of the increase in new fi ndings. In this international mini- symposium, in addition to auditory neuropathy, vestibular neuropathy in particular was discussed because of the simultaneous existence of both auditory and vestibu- lar issues. This book provides up-to-date information and knowledge on the neuropathy of auditory and vestibular eighth nerves VIII. The title for the book was suggested by Prof. Arnold Starr as one that would cover the entire range of topics. I am hopeful that, with this book, readers can gain insight into the new disease entity, auditory and vestibular neuropathy. I would like to acknowledge, with gratitude, that this publication was fi nancially supported in part by the alumni association of the Department of Otolaryngology, Faculty of Medicine, University of Tokyo, and by the Society for the Promotion of Oto-Rhino-Laryngology.

  • DISORDERS of AUDITORY PROCESSING: EVIDENCE for MODULARITY in AUDITION Michael R
    DISORDERS OF AUDITORY PROCESSING: EVIDENCE FOR MODULARITY IN AUDITION Michael R. Polster and Sally B. Rose (Psychology Department, Victoria University of Wellington, Wellington, New Zealand) ABSTRACT This article examines four disorders of auditory processing that can result from selective brain damage (cortical deafness, pure word deafness, auditory agnosia and phonagnosia) in an effort to derive a plausible functional and neuroanatomical model of audition. The article begins by identifying three possible reasons why models of auditory processing have been slower to emerge than models of visual processing: neuroanatomical differences between the visual and auditory systems, terminological confusions relating to auditory processing disorders, and technical factors that have made auditory stimuli more difficult to study than visual stimuli. The four auditory disorders are then reviewed and current theories of auditory processing considered. Taken together, these disorders suggest a modular architecture analogous to models of visual processing that have been derived from studying neurological patients. Ideas for future research to test modular theory more fully are presented. Key words: auditory processing, modularity, review INTRODUCTION Neuropsychological investigations of patients suffering from brain damage have flourished in recent years and helped to produce more detailed and neuroanatomically plausible models of several aspects of cognitive function. For example, models of language processing are often closely aligned with studies of aphasia (e.g., Caplan, 1987; Goodglass, 1993) and models of memory draw heavily upon studies of amnesia (e.g., Schacter and Tulving, 1994; Squire, 1987). Most of this research has relied on visually presented materials, and as a result visual processing disorders tend to be more well-documented and better understood than their auditory counterparts.

  • Cortical Auditory Disorders: Clinical and Psychoacoustic Features
    J Neurol Neurosurg Psychiatry: first published as 10.1136/jnnp.51.1.1 on 1 January 1988. Downloaded from Journal of Neurology, Neurosurgery, and Psychiatry 1988;51:1-9 Cortical auditory disorders: clinical and psychoacoustic features MARIO F MENDEZ,* GEORGE R GEEHAN,Jr.t From the Department ofNeurology, Case Western Reserve University, Cleveland, Ohio,* and the Hearing and Speech Center, Rhode Island Hospitalt, Providence, Rhode Island, USA SUMMARY The symptoms of two patients with bilateral cortical auditory lesions evolved from cortical deafness to other auditory syndromes: generalised auditory agnosia, amusia and/or pure word deafness, and a residual impairment of temporal sequencing. On investigation, both had dysacusis, absent middle latency evoked responses, acoustic errors in sound recognition and match- ing, inconsistent auditory behaviours, and similarly disturbed psychoacoustic discrimination tasks. These findings indicate that the different clinical syndromes caused by cortical auditory lesions form a spectrum of related auditory processing disorders. Differences between syndromes may depend on the degree of involvement of a primary cortical processing system, the more diffuse accessory system, and possibly the efferent auditory system.

  • From Hearing Sounds to Recognizing Phonemes: Primary Auditory Cortex Is a Truly Perceptual Language Area
    AIMS Neuroscience, 3 (4): 454–473. DOI: 10.3934/Neuroscience.2016.4.454 Received 11 August 2016, Accepted 31 October 2016, Published 9 November 2016 http://www.aimspress.com/journal/neuroscience Review From Hearing Sounds to Recognizing Phonemes: Primary Auditory Cortex is A Truly Perceptual Language Area Byron Bernal 1 and Alfredo Ardila 2, * 1 Radiology Department/Brain Institute, Nicklaus Children’s Hospital, Miami, FL, USA; 2 Department of Communication Sciences and Disorders, Florida International University, Miami, Florida, USA * Correspondence: Email: [email protected]; Tel: (305)-348-2750; Fax: (305)-348-2710 Abstract: The aim of this article is to present a systematic review about the anatomy, function, connectivity, and functional activation of the primary auditory cortex (PAC) (Brodmann areas 41/42) when involved in language paradigms. PAC activates with a plethora of diverse basic stimuli including but not limited to tones, chords, natural sounds, consonants, and speech. Nonetheless, the PAC shows specific sensitivity to speech. Damage in the PAC is associated with so-called “pure word-deafness” (“auditory verbal agnosia”). BA41, and to a lesser extent BA42, are involved in early stages of phonological processing (phoneme recognition). Phonological processing may take place in either the right or left side, but customarily the left exerts an inhibitory tone over the right, gaining dominance in function. BA41/42 are primary auditory cortices harboring complex phoneme perception functions with asymmetrical expression, making it possible to include them as core language processing areas (Wernicke’s area). Keywords: Brodmann areas 41/42; phonological perception; word-deafness; language understanding; Wernicke’s area 455 1. Introduction Comprehension of verbal information has been approached from different perspectives across time.

    Using fMRI and Behavioural Measures to Investigate Rehabilitation in Post-Stroke Aphasic Deficits Sonia Leslie Elaine Brownsett 2013 Imperial College London, Department of Medicine This thesis is submitted for the degree of Doctor of Philosophy 1 Acknowledgments Firstly, I would like to thank all the volunteers that participated in my studies, especially the patients. Thanks also to the C3NL lab (past and present) for their support, especially those that appreciated the trials and tribulations of stroke studies. I would also like to thank David Howard, for his support, sensible perspective and for pointing me in the direction of this PhD. The largest dose of gratitude must go to Professor Wise (honFRCSLT) for his unique supervisory style, which has supported and encouraged throughout many a difficult result. I’m sure the sense of futility was mutual but he did a remarkable job of being optimistic and was, indeed, proved right in the end. I must also thank my family for their obvious contribution, but most importantly Tony and Thomas for their continued unconditional support and patience at many a missed bedtime. To Hannah, Noah, Joshua, Erin, Niall, Isla, Sophie and Thomas. 2 Statement of Publications The results from this thesis have been submitted for publication. The results presented in Chapter Three have been submitted to Brain and Language and are currently under review.

Focal neurological signs such as pa- resis, aphasia or visual field deficits together with often serious general state of a neurological patient usually push auditory symptoms into the background. Here, we present a review of literature on central and peripheral auditory disturbances that can appear in the course of most common neurological diseases. We present: cerebral stroke, co- chleovestibular nerve compression syndrome, cerebral palsy, multiple sclerosis, epilepsy, myasthenia gravis and brain tumors. We focus on the neuroanatomical basis of auditory dysfunctions, their character and prevalence typical for the abovementioned diseases. Theoretical considerations are supported by broad audiological and neuroimaging studies of our patients. Auditory symptoms in neurological diseases seem to be rare. However, knowledge of these symptoms and their origin can be helpful in proper diagnosis and comprehensive patient management.

  • Gidado Jennifer Busayo 18/Mhs01/166 Nursing Physiology
    GIDADO JENNIFER BUSAYO 18/MHS01/166 NURSING PHYSIOLOGY Discuss the physiology of balance The vestibular system is the sensory apparatus of the inner ear that helps the body maintain its postural equilibrium. The information furnished by the vestibular system is also essential for coordinating the position of the head and the movement of the eyes. There are two sets of end organs in the inner ear, or labyrinth: the semicircular canals, which respond to rotational movements (angular acceleration); and the utricle and saccule within the vestibule, which respond to changes in the position of the head with respect to gravity (linear acceleration). The information these organs deliver is proprioceptive in character, dealing with events within the body itself, rather than exteroceptive, dealing with events outside the body, as in the case of the responses of the cochlea to sound. Functionally these organs are closely related to the cerebellum and to the reflex centres of the spinal cord and brainstem that govern the movements of the eyes, neck, and limbs. Although the vestibular organs and the cochlea are derived embryologically from the same formation, the otic vesicle, their association in the inner ear seems to be a matter more of convenience than of necessity. From both the developmental and the structural point of view, the kinship of the vestibular organs with the lateral line system of the fish is readily apparent. The lateral line system is made up of a series of small sense organs located in the skin of the head and along the sides of the body of fishes.
