Continuous time wavelet entropy of auditory evoked potentials

On wavelet analysis of auditory evoked potentials.

OBJECTIVE To determine a preferred wavelet transform (WT) procedure for multi-resolution analysis (MRA) of auditory evoked potentials (AEP). METHODS A number of WT algorithms, mother wavelets, and pre-processing techniques were examined by way of critical theoretical discussion followed by experimental testing of key points using real and simulated auditory brain-stem response (ABR) waveforms...

Brainstem 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...

Speech 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 ...
