o Auditory evoked potentials (AEPs) are changes in electrical activity (measured as potentials or
voltages) generated in the ear or brain in r
Sounds of cochlear origin recorded with a mic tightly coupled to the EC.
The increase of AEP amp with response latency is due to a larger
population of neurons involved, and their close relation to the recording
How to do the ABR assignment Questions!
1. Look at your Right ear and left ear and write your latencies for I, III, V. Get a ruler and measure
your peak-to-trough for wave I, for wave III and wave V convert to microvolts using the scale on
the side of you
Measure transtympanic electrode at the promontory
Measure tympanic membrane electrode on the TM
N1 and N2 of the CAP (compound action potential) have the same
generators of wave I & II of ABR (SGC & IC AN)
