UNLABELLED Studies about cortical auditory evoked potentials using the speech stimuli in normal hearing individuals are important for understanding how the complexity of the stimulus influences the characteristics of the cortical potential generated. OBJECTIVE To characterize the cortical auditory evoked potential and the P3 auditory cognitive potential with the vocalic and consonantal contra...

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. ...

A 13-year-old boy with imipramine overdose developed seizures, respiratory arrest, and coma. Abnormalities of oculovestibular reflexes, electroencephalograms, and brainstem auditory evoked potentials were monitored in relation to measurements of drug levels. An alpha-coma electroencephalographic pattern evolved into one evidencing spindle coma and eventually into a normal pattern. Prolonged bra...

Herein, we report a case of multiple sclerosis in which peripheral and central hearing, were evaluated through early (brainstem), middle and late auditory evoked potentials before and after corticosteroid therapy. Auditory evaluation revealed better performance on all post-treatment tests. In this case, central auditory function tests (behavioral and electrophysiological) identified the locatio...

The cochlear outer hair cells serve a tuning function, and any dysfunction of their electromotile response can be reflected in language disorders. Otoacoustic emissions can be used to determine any dysfunction of these cells. A set of clinical records was established to register the neurological and auditory functioning in 42 children, followed by assessment with the Wechsler Intelligence Scale...
