What are the three general techniques for recording the auditory evoked potentials?
Rate each of theirs reliability as excellent, good, fair. |
1) Electrocochleograph (ECoG) - excellent reliablity
2) Auditory Brainstem Response (ABR) audiometry - good 3) Cortical Electrical Response (CER) audiometry - fair |

What are the auditory structures that generate auditory brainstem response of waves I - VI? (use the mnemonic...)
|
Wave I – generated by cranial nerve VIII
Wave II – generated by the cochlear nucleus Wave III – generated by the superior olivary complex Wave IV – generated by the lateral lemniscus Wave V – generated by the inferior colliculus ***Mnemonic is E COLI |
|
|
Which portion of the auditory system is tested by the electrocochleography technique?
|
peripheral nerve and cochlea
|
|
|
Which portion of the auditory system is tested by the auditory brain stem technique?
|
Brain stem and periphery
|
|
|
Which portion of the auditory system is tested by the cortical evoked response technique?
|
entire, depending on response
|
|
|
The most sensitive recording in electrocochleography are obtained how?
|
with a needle electrode placed through the TM (transtympanic ECoG) on the bone of the promontory
|
|
|
Why is electrocochleography the most accurate and sensitive of the ERA techniques?
|
by virtue of the close placement of the electrode to the generator site.
|
|
|
Which of the three electrical response audiometry techniques are not affected by anesthesia or sleep?
|
electrocochleography and ABR
