T/F: In near field recording as you move the electrode away from the site of the EP of interest the latency of the response decreases
False. Far field response has to do with latency
Name a few of several ways to assess the ABR (analysis parameters) for diagnostic purposes.
1. Interpeak latencies (most important)
2. Absolute latency
3. interaural differences
what is the primary difference between the ipsilateral and contralateral recordings on an ABR?
Wave I (present on ipsilateral side.) Negative wave is present on contralateral side
What waveform component(s) of the conventional ABR are thought to be generated from the peripheral auditory system?
What are the advantages of an earclip verses a surface electrode placed on sternocleidomastoid muscle
less electrical contamination (muscle)
T/F: the ABR is a test of neural synchrony
T/F: the acoustic click is a broadband stimulus
What is a click stimulus used for ABR assessment?
Because it illicits synchronous neural firing across a wide range of the cochlea
T/F: The ABR best correlates to pure tone hearing in the 2K-4K Hz range
true. especially noticeable in Wave I***
T/F: typically there are three electrodes used to conduct a one channel ABR. Tow of the three electrodes are considered active
