1. Changes in late-latency auditory evoked potentials after tinnitus suppression using auditory stimulation
Abstract Objective: Tinnitus can result from auditory system reorganization due to neural activity dysfunctions. Auditory stimulation can cause temporary or persistent tinnitus alleviation by altering the neural generators. The present study investigated the changes in Late-Latency Auditory Evoked Potentials (LLAEPs) after tinnitus suppression using auditor

2. The Relationship between the Etiology of Profound Prelingual Sensorineural Hearing Loss and the Results of Vestibular-Evoked Myogenic Potentials
Abstract Introduction Cervical vestibular-evoked myogenic potentials (cVEMPs) are biphasic, short latency potentials, which represent the inhibition of the contraction of the sternocleidomastoid muscle (SCM) mediated by the saccule, the inferior vestibular nerve, the vestibular nuclei and the medial vestibular spinal tract. Objective To evaluate the resp

3. Monitoring auditory cortical plasticity in hearing aid users with long latency auditory evoked potentials: a longitudinal study
OBJECTIVE: The objective of this study was to compare long-latency auditory evoked potentials before and after hearing aid fittings in children with sensorineural hearing loss compared with age-matched children with normal hearing. METHODS: Thirty-two subjects of both genders aged 7 to 12 years participated in this study and were divided into two groups as

4. Ocular Vestibular Evoked Myogenic Potentials
Introduction Diagnostic testing of the vestibular system is an essential component of treating patients with balance dysfunction. Until recently, testing methods primarily evaluated the integrity of the horizontal semicircular canal, which is only a portion of the vestibular system. Recent advances in technology have afforded clinicians the ability to as

5. Eletrofisiologia da audição em indivíduos com vestibulopatias periféricas pré e pós reabilitação vestibular / Electrophysiological evaluation of hearing in individuals with peripheral vestibular disorders before and after vestibular rehabilitation therapy
INTRODUCTION: The auditory evoked potentials assess the neuroelectrical activity of the auditory pathway from the auditory nerve to the cerebral cortex. The vectoelectronystagmography analyzes the semicircular canals and/or inferior vestibular nerve, checking peripheral or central vestibular involvement. The vestibular rehabilitation therapy consists in acti

6. Estudo dos potenciais evocados auditivos em indivíduos com queixa de zumbido / Study of auditory evoked potentials in individuals with tinnitus complaint
INTRODUCTION: attempting to elucidate some aspects related to tinnitus, the hypothesis of alteration in the central auditory pathways was raised. Thus, auditory evoked potentials may represent an alternative to detect possible central auditory disorders that may be present in this population and that indicate the probable generator site of such symptom. AIM:

7. Ondaletas no processamento de potenciais evocados somato-sensitivos. / Wavelets in somatosensory evoked potential processing.
Os potenciais evocados somato-sensitivos são úteis para detectar e localizar lesões nas vias sensoriais. Sua obtenção exige a média síncrona de mais de mil respostas individuais. A redução do número de estímulos elétricos para obter o potencial evocado resulta na diminuição do tempo do exame e do desconforto do paciente. O objetivo desta disser

8. 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

9. 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

10. O emprego do potencial de longa latencia (P3) no diagnostico de complicações neurologicas e psiquicas do lupus eritematoso sistemico : comparação com a avaliação clinica e neuropsicologica
In an attempt to correlate neurological and neuropsychological findings with long-latency (endogenous) evoked potentials parameters, thirty-three female patients with a diagnosis of systemic lupus erythematosus were studied as to their visual auditory (brainstem), somatosensory (short latency and cortical) and long-latency (endogenous, P300) auditory evoked

11. Abnormalities of proximal conduction in acute idiopathic polyneuritis: comparison of short latency evoked potentials and F-waves.
Motor and sensory conduction studies, F-wave latency, and the latency of evoked potentials from the brachial plexus and cervical spine in response to median nerve stimulation were examined in 17 patients with acute idiopathic polyneuropathy. Short latency evoked potentials provided a higher yield of evidence of abnormalities of proximal conduction than did t

12. Electrophysiologic recordings in a patient with a discrete unilateral thalamic infarction
The electroencephalogram, and somatosensory and auditory evoked potentials were recorded from a patient, who, at necropsy, showed a restricted unilateral thalmic infarct involving predominantly the anterior and lateral thalamus. The electroencephalogram showed distinct monomorphic delta activity and a suppression of the alpha rhythm over the side of the lesi
