The effect of visual and audiovisual competition on the auditory N1-P2 evoked potential.
BACKGROUND Use of a competition stimuli (e.g., video) in clinical settings is a widespread practice, yet the effects of these stimuli on evoked potentials are not well understood. PURPOSE The present investigation acquired the click evoked auditory N1-P2 in quiet and in two types of competition: during presentation of an unrelated visual stimulus or audiovisual stimulus. Responses were acquir...
متن کاملEffects of discrimination task difficulty on N1 and P2 components of late auditory evoked potential.
The present study investigated the question of whether, in healthy young listeners, increases in discrimination task difficulty will alter the amplitude of either the N1 or P2 components of the late auditory evoked potential (LAEP). Using a stimulus oddball procedure, listeners discriminated changes in the frequency of ongoing tonal stimuli. On different test runs, task difficulty was manipulat...
متن کاملAuditory N1-P2 Cortical Event Related Potentials in Auditory Neuropathy Spectrum Disorder Patients
MATERIALS and METHODS: Cortical auditory evoked potentials were obtained from nine female and seven male patients with auditory neuropathy, ranging in age from 19 to 48 years. The control group comprised 15 (9 males and 6 females) age-matched, normally hearing adults. Cortical auditory evoked potentials were recorded in both groups. Audiological assessments were performed in both groups, which ...
متن کاملDevelopmental changes in refractoriness of the cortical auditory evoked potential.
OBJECTIVE This study examined morphological changes in the cortical auditory evoked potential (CAEP) waveform as a function of varying stimulation rate. Stimuli were presented in a paradigm which indirectly assesses the refractory properties of the underlying neuronal generators. METHODS CAEPs were recorded in 50 normal-hearing children (3-12 years) and 10 young adults (24-26 years). A speech...
متن کاملAutomated cortical auditory evoked potentials threshold estimation in neonates.
INTRODUCTION The evaluation of Cortical Auditory Evoked Potential has been the focus of scientific studies in infants. Some authors have reported that automated response detection is effective in exploring these potentials in infants, but few have reported their efficacy in the search for thresholds. OBJECTIVE To analyze the latency, amplitude and thresholds of Cortical Auditory Evoked Potent...
