INTRODUCTION Residual inhibition (RI) is the temporary inhibition of tinnitus by use of masking stimuli when the device is turned off. OBJECTIVE The main aim of this study was to evaluate the effects of RI induced by auditory electrical stimulation (AES) in the primary auditory pathways using early auditory-evoked potentials (AEPs) in subjective idiopathic tinnitus (SIT) subjects. MATERIALS...

The auditory brain stem response to speech mimics the acoustic characteristics of the speech signal with remarkable fidelity. This makes it possible to derive from it considerable theoretical and clinically applicable information relevant to auditory processing of complex stimuli. Years of research have led to the current characterization of these neural events with respect to the underlying ac...

Objective: There are various known hormone-related effects on audiometric thresholds and other auditory measures; however, research is scarce and mixed on the effect of pregnancy on the early-, mid-, and late-latency auditory evoked responses in a longitudinal fashion. Of clinical importance is to know whether electrophysiologic measures during pregnancy may further alter the results of, or mas...

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....

Background: Brainstem auditory evoked responses (BAERs) are electrophysiological investigations have widespread clinical utility in neurology, audiology, neonatology and anesthesiology. BAER responses exhibit a normal variability due to various non-pathologic factors and age is one of the variables suggested to have considerable influence on normal BAE responses. Aging changes in the auditory s...

The responses of neuronal clusters to amplitude-modulated tones were studied in five auditory cortical fields of the anesthetized cat: the primary auditory field (AI), second auditory field (AII), anterior auditory field (AAF), posterior auditory field (PAF) and the ventro-posterior auditory field (VPAF). Modulation transfer functions (MTFs) for amplitude-modulated tones were obtained at 172 co...
