Comparison of click and CE-chirp stimuli on Brainstem Auditory Evoked Potential recording Comparação dos estímulos clique e CE-chirp no registro do Potencial Evocado Auditivo de Tronco Encefálico

Potencial evocado auditivo de tronco encefálico com estímulo de fala***** Brainstem auditory evoked potential with speech stimulus

Background: although clinical use of the click stimulus for the evaluation of brainstem auditory function is widespread, and despite the fact that several researchers use such stimulus in studies involving human hearing, little is known about the auditory processing of complex stimuli such as speech. Aim: to characterize the findings of the Auditory Brainstem Response (ABR) performed with speec...

Padronização do potencial evocado auditivo de tronco encefálico utilizando um novo equipamento***** Standardization of brainstem auditory evoked potential using a new device

Background: standardization of Brainstem Auditory Evoked Potential (BAEP) using a new device. Aim: to standardize BAEP responses using a new device developed (NDD) in Brazil. Method: analysis of absolute latencies, interpeaks and wave amplitudes of BAEP, using a new device developed to study normal-hearing groups (91 adults) and individuals (15 adults) with bilateral neurosensory hearing loss. ...

Estudo Do Efeito De Supressão No Potencial Evocado Auditivo De Tronco Encefálico***** Study of Suppression Effect in the Brainstem Auditory Evoked Potential Introduction

Background: the suppression effect with contralateral white noise observed in the brainstem auditory evoked potential can be influenced by the efferent auditory system. Aim: to evaluate the suppression effect with contralateral white noise in the Brainstem Auditory Evoked Potential of individuals with normal hearing. Methods: 25 individuals, ranging in age from 18 to 30 years, of both genders, ...

Auditory Brainstem Response (ABR) Findings With Click and CE-Chirp Stimulations in Noise-Exposed Participants

Potencial evocado auditivo de tronco encefálico em gerbils submetidos à isquemia e sepse

Introduction: An ischemic stroke is a clinical condition that affects thousands of people worldwide. As a result of this injury, neuronal death can be observed, and in the natural course of recovery, the individual may develop sepsis. Sepsis is a systemic inflammatory response that can lead the patient to death. To assess the clinical condition of a patient with this condition, the Auditory Bra...
