متن کاملBrainstem Auditory Evoked Potentials
Brainstem auditory evoked potentials (BAEPs) are electrical field potentials generated by stimulation of the auditory pathways. With repetitive auditory stimulation, reproducible electrical potentials can be elicited and recorded from scalp electrodes. These waves are generated by specific brain regions and occur at predictable intervals. Clinically, this neurophysiological property is useful t...
متن کاملARX-derived auditory evoked potential index and bispectral index during the induction of anesthesia with propofol and remifentanil.
UNLABELLED A new commercial auditory evoked potential (AEP) monitor (A-line AEP monitor) was developed to calculate an index (ARX AEP index; AAI) by automatically using the amplitudes and latencies of the AEP. We investigated 30 patients before spine surgery. AAI; bispectral index (BIS); relative (%) delta, theta, alpha, and beta; spectral edge frequency; median frequency; mean arterial blood p...
متن کاملChanges in the rapidly extracted auditory evoked potentials index and the bispectral index during sedation induced by propofol or midazolam under epidural block.
BACKGROUND The bispectral index (BIS) and the rapidly extracted auditory evoked potentials index (A-line ARX Index or AAI) have been proposed as methods to measure the depth of sedation. A prospective study was designed to assess the performance of both these methods for measuring the depth of sedation induced by propofol or midazolam under epidural block. METHODS Thirty-two ASA I and II adul...
متن کاملSpeech Specific Auditory Evoked Potentials
ERPs of 27 scalp electrodes were recorded from fourteen volunteers during the presentation of binaurally presented speech and non-speech stimuli. Speech stimuli consisted of nine different consonant-vowel syllables. Non-speech stimuli were generated using special envelope-modulated low pass noise. With this method, kinematic signals are time and amplitude normalized, allowing us to observe the ...
