Acoustic sensitivity of the vestibular apparatus is well-established, but the contribution of vestibular receptors to the late auditory evoked potentials of cortical origin is unknown. Evoked potentials from 500 Hz tone pips were recorded using 70 channel EEG at several intensities below and above the vestibular acoustic threshold, as determined by vestibular evoked myogenic potentials (VEMPs)....

Hearing loss, frequently with tinnitus, is the main symptom of acoustic neuromas (ANs), which compress the cochlear nerve and affect the cochlear blood supply. This vascular mechanism explains why atypical, fluctuating deafness, with audiometric features of retrocochlear involvement, may occur in this condition. An early diagnosis of ANs is essential for a good prognosis. Physicians should reco...

The objectives were to study ultrasound (US), magnetic resonance imaging (MRI), single photon emission tomography (SPET) and brainstem auditory evoked potentials (BAEP) as structural and functional imaging methods for the prediction of later neuromotor outcome and to assess the reliability of auditory brainstem responses (ABR), transient evoked otoacoustic emissions (TEOAE) and free-field audit...

Auditory distraction is a failure to maintain focus on a stream of sounds. We investigated the neural correlates of distraction in a selective-listening pitch-discrimination task with high (competing speech) or low (white noise) distraction. High-distraction impaired performance and reduced the N1 peak of the auditory Event-Related Potential evoked by probe tones. In a series of simulations, we...

BACKGROUND Glycine inhibits the formation of advanced glycation end products that may cause central and peripheral neuronal damage, affecting also the auditory nerve. AIM To evaluate the effect of glycine on auditory nerve conduction and hearing level among patients with type 2 diabetes mellitus and auditory neuropathy. MATERIAL AND METHODS Twenty grams of oral glycine per day were administ...

INTRODUCTION Evaluation of cortical auditory evoked potentials in children with cochlear implants has been proven to be an effective method for assessing cortical maturation after electrical stimulation. OBJECTIVE To analyze the changes in latency values of cortical auditory evoked potentials before and three months after cochlear implant use. MATERIAL AND METHODS This was a case-control st...

BACKGROUND auditory evoked potentials. AIM to describe the results of brainstem auditory evoked potentials (PEATE), middle latency auditory evoked potentials (PEAML) and cognitive potential (P300) in individuals over 50 years. METHOD this study was developed at the Speech and Hearing Investigation Laboratory in Auditory Evoked Potentials of the Speech-Language and Hearing Course of the Depa...
