Cortical evoked response audiometry
WebThe authors refer their results obtained with brainstem-evoked response audiometry (BSERA) and behavioral audiometry in a group of 270 children (aged from 6 months to 12 years) divided into subjects with (group A) and without (group B) reliable audiograms. In group A an agreement between the two methods was found in 77% of cases and a … WebCortical evoked response audiometry is adequate for approximating hearing threshold levels with frequency specificity when the psychoacoustic responses lack reliability and reproducibility (compensation claim). It is well-known that control of wakefulness is essential for the reliability of slow vertex responses (SVR). Therefore, sedative ...

WebMar 1, 2009 · Neural response telemetry and intra-operative electrical auditory brainstem recording have been routinely performed by implant programs for many years. Recently, there has been great interest in potential clinical applications of cortical auditory evoked potentials in the implant field.
WebMEG results showed similar cortical sites for the ON and OFF responses. There was a dominant ON response with stronger phase-locking factor (PLF) in the alpha (8–14 Hz) and theta (4–8 Hz) bands for the damped sounds. ... Both the phase locking factor and the auditory evoked response measures capture information about neural synchrony … WebObjective: The effect of long term auditory deprivation on Cortical Auditory Evoked Potentials (CAEPs) especially in human models is not well explored. ... Conclusion: The …
WebThey may also be useful for describing auditory system cortical plasticity development. AERP responses influence the sound detection process and transient-type sound encoding of physical features of auditory stimuli. ... Measurement of auditory evoked responses has been used in the investigation of vestibular neurinomas, MS, and intrinsic ... WebBackground: Previous studies have demonstrated that cortical auditory-evoked potentials (CAEPs) can be reliably elicited in response to speech stimuli in listeners wearing hearing aids. It is unclear, however, how close to the aided behavioral threshold (i.e., at what behavioral sensation level) a sound must be before a cortical response can reliably be …
WebMar 29, 2000 · The acoustic change complex (ACC) is a scalp-recorded negative–positive voltage swing elicited by a change during an otherwise steady-state sound. The ACC was obtained from eight adults in response to changes of amplitude and/or spectral envelope at the temporal center of a three-formant synthetic vowel lasting 800 ms. In the absence of …
