13. Diagnosis and management of somatosensory tinnitus: review article
Tinnitus is the perception of sound in the absence of an acoustic external stimulus. It affects 10-17% of the world's population and it a complex symptom with multiple causes, which is influenced by pathways other than the auditory one. Recently, it has been observed that tinnitus may be provoked or modulated by stimulation arising from the somatosensorial s

14. Potencial evocado auditivo de tronco encefálico com estímulo de fala em crianças com distúrbio fonológico / Speech-evoked auditory brainstem responses in children with phonological disorders
INTRODUCTION: The Auditory Brainstem Response (ABR) is an objective measure that evaluates the integrity of the brainstem auditory pathway and that supplements the routine audiological procedures in the diagnosis of hearing impairment. Nowadays, studies have been developed in order to characterize the auditory evoked potentials obtained through speech stimul

15. PROCESSAMENTO AUDITIVO DE MILITARES EXPOSTOS A RUÍDO OCUPACIONAL: UM ESTUDO LONGITUDINAL. / AUDITORY PROCESSING OF MILITARY PERSONNEL EXPOSED TO OCCUPATIONAL NOISE: A LONGITUDINAL STUDY
The hearing evaluation that has been doing on occupational environment easily detects the noise induced hearing loss (NIHL), however, alterations on the central auditory pathway can not be observed. Studies have showed a relation between the noise exposure time and the increase of the incidence of hearing loss, but do not demonstrate how the auditory process

16. Zumbido e audição normal: estudo do reflexo acústico e da supressão das emissões otoacústicas
Introduction: The functioning of the auditory pathway of patients with tinnitus complaints and normal hearing can be directly related to a mal-functional in the auditory efferent pathway, regarding the level of the olivocochlear superior system, in which, the acoustic reflex threshold data and the otoacustic emissions with contralateral noise may represent a

17. Influência da idade na atividade do trato olivococlear medial eferente sobre as propriedades mecânicas da cóclea em indivíduos ouvintes normais / Age influence in the activity of medial efferent olivocochlear tract upon mechanical properties of cochlea in normal hearing individuals
Medial olivocochlear tract makes the efferent control of the outer hair cells, controlling the slow contractions and mitigating rapid contractions. Upon the appearance of techniques for the investigation of the amplitude of otoacoustic emissions with and without acoustic stimulation against, ipsi and bilaterally, it is now possible to stimulate clinically th

18. Efferences of lateral superior olive nucleus in the rat ( rattus norvegicus) / Eferências do núcleo lateral superior da oliva no rato (rattus norvegicus).
Após a descrição da Urocortina 1, um neuropeptídeo encontrado principalmente no núcleo de Edinger-Westphal e no núcleo lateral superior da oliva (LSO), atentou-se para a ausência do conhecimento das projeções de ambos os núcleos. Nós pretendemos contribuir para o conhecimento das projeções ascendentes e descendentes do LSO, usando um traçador n

19. Audiological and electrophysiological evaluation of children with acquired immunodeficiency syndrome (AIDS)
We examined the peripheral auditory system and the auditory brainstem pathway of children with Acquired Immunodeficiency Syndrome (AIDS). One hundred and one children, 51 with AIDS diagnosis and 50 normal children were evaluated. Audiological assessment included immittance measures, pure tone and speech audiometry and auditory brainstem response (ABR). The c

20. Behavioral, electroacoustic and electrophysiological assessment of hearing in autism. / "Avaliação comportamental, eletroacústica e eletrofisiológica da audição em autismo"
INTRODUCTION: Autism is a disorder, which begins in the infancy, and the main characteristics are the presence of an abnormal or impaired development of social interaction and communication, and restrict range of activities and interest. Some theories consider autism as a developmental disorder caused by a central nervous system alteration, and stress the pr

21. Electrophysiological hearing evaluation in children with phonological disorder pre and post speech therapy / Avaliação eletrofisiológica da audição em crianças com distúrbio fonológico pré e pós terapia fonoaudiológica
INTRODUCTION: the phonological disorder is a speech disorder that may occur in one or more levels that are responsible for the development of the phonological system. Such levels are: speech production and perception, and rules organization. For a normal development of the phonological system, as well as of other aspects of language, it is necessary the inte

22. Interpretação clínica do potencial evocado auditivo do tronco encefálico na frequência específica de 1000Hz em recém nascidos
Objective: To Establish normative data for clinical interpretation of frequency specific auditory brainstem response in 1000Hz, in full term newborns under 1 month of age, to be based on protocol by Hood (1998) and adapted to attended population on DERDIC. Method: Auditory brainstem response (ABR) stimulus click and toneburst 1000Hz, were performed in 10 new

23. Traces of learning in the auditory localization pathway
One of the fascinating properties of the central nervous system is its ability to learn: the ability to alter its functional properties adaptively as a consequence of the interactions of an animal with the environment. The auditory localization pathway provides an opportunity to observe such adaptive changes and to study the cellular mechanisms that und

24. Song-selective auditory circuits in the vocal control system of the zebra finch.
Birdsong is a learned behavior controlled by a distinct set of brain nuclei. The song nuclei known as area X, the medial nucleus of the dorsolateral thalamus (DLM), and the lateral magnocellular nucleus of the anterior neostriatum (L-MAN) form a pathway that plays an important but unknown role in song learning. One function served by this circuit might be au
