1. The effect of noise on the amplitude and morphology of cortical auditory evoked potentials
Abstract Objective: To analyze the effect of noise on electrophysiological measurements (P1-N1-P2 complex) of cortical auditory evoked potentials in normal hearing individuals of different ages. Methods: The inclusion criteria for the study were young individuals, adults and elderly, aged 18–75 years, with auditory thresholds up to 25 dB. Participants we

2. Effectiveness of galvanic vestibular evoked myogenic potential for evaluation of Meniere’s disease
Abstract Objectives: Although the cause of Meniere’s disease (MD) is not fully understood, endolymphatic hydrops is widely believed to be responsible for MD. Previous studies have used Air-Conducted Sound (ACS)-induced Vestibular Evoked Myogenic Potentials (VEMPs) to evaluate otolithic function in patients with MD. However, the use of Galvanic Vestibular

3. 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

4. Cortical Reorganization Following Psychoeducational Counselling and Residual Inhibition Therapy (RIT) in Individuals with Tinnitus
Abstract Introduction Psychoeducational counselling and residual inhibition therapy (RIT) are traditional approaches used in many clinics to manage tinnitus. However, neurophysiological studies to evaluate posttreatment perceptual and functional cortical changes in humans are scarce. Objectives The present study aims to explore whether cortical auditory-ev

5. Galvanic vestibular evoked myogenic potentials: normative data and the effect of age
Resumo Introdução: Os potenciais evocados miogênicos vestibulares galvânicos avaliam as respostas do nervo vestibular com estimulação elétrica por meio de registros coletados do músculo esternocleidomastóideo. Uma resposta normal de potenciais evocados miogênicos vestibulares consiste nos primeiros picos positivo, P1, e negativo, N1. A resposta po

6. Long-term Effects of Unilateral and Bilateral Otitis Media and Myringotomy on Long-Latency Verbal and Non-Verbal Auditory-Evoked Potentials
Abstract Introduction Otitis media (OM) is considered one of the most common reasons patients seek medical care in childhood. The fluctuating nature of hearing loss in cases of OM leads to irregular sound stimulation of the central auditory nervous system. Objectives To analyze the long-latency auditory-evoked potential (LLAEP) by verbal and nonverbal soun

7. Masking Level Difference and Electrophysiological Evaluation in Adults with Normal Hearing
Abstract Introduction The auditory structures of the brainstem are involved in binaural interaction, which contributes to sound location and auditory figure-background perception. Objective To investigate the performance of young adults in the masking level difference (MLD) test, brainstem auditory-evoked potentials (BAEPs) with click stimulus, and frequen

8. Estudo do potencial evocado auditivo de tronco encefálico com estímulo de fala na população pediátrica com e sem transtornos de linguagem oral: uma revisão sistemática
Resumo Introdução: O potencial evocado auditivo de tronco encefálico com estímulo de fala (PEATE-fala) tem sido aplicado para observar como os sons da fala se manifestam no tronco encefálico. Essa ferramenta pode ser usada em crianças na avaliação do processamento auditivo central, permite intervenções preventivas e precoces. Objetivo: Conhecer o

9. Cortical Auditory Evoked Potentials in 2-Year-Old Subjects
Abstract Introduction Cortical auditory evoked potentials (CAEPs) can be used to evaluate both peripheral and cortical components of auditory function, and contribute to the assessment of functional sensitivity and auditory thresholds, especially in neonates and infants. Auditory evoked potentials reflect auditory maturity and precede the acquisition of mor

11. Application of Cervical Vestibular-Evoked Myogenic Potentials in Adults with Moderate to Profound Sensorineural Hearing Loss: A Preliminary Study
Abstract Introduction The cochlea and the vestibular receptors are closely related in terms of anatomy and phylogeny. Patients with moderate to profound sensorineural hearing loss (MPSHL) should have their vestibular organ functions tested. Objective To evaluate the incidence of vestibular abnormalities in patients with MPSHL and to study the correlation

12. Pure-Tone Hearing Thresholds and Brainstem Auditory Evoked Potentials in Sporadic Ataxia
Abstract Introduction Spinocerebellar ataxia (SCA) is part of a genetic and clinical heteroge- neous group of neurodegenerative diseases characterized by progressive cerebellar ataxia. Objective To describe the results of audiological and electrophysiological hearing evaluations in patients with sporadic ataxia (SA). Methods A retrospective cross-secti
