EEG and auditory evoked potentials
1.
Frontal cortex and association areas; late cortical response
●
1a = P1
●
1b = N1
●
1c = P2
●
1d = N2
2.
Medial geniculate and primary auditory cortex; early cortical response
●
2a = No
●
2b = Po
●
2c = Na
●
2d = Pa
●
2e = Nb
3.
Acoustic nerve and brain stem; brain stem response
AEP troubleshooting
Problem
Solution
Why are there no clicks to be heard from the
earphones/headphones?
The connector is not in place.
●
Check that the plug is firmly pushed into the
appropriate connector in the headbox.
What if all or most of the EP epochs are rejected?
The signal has too much noise or artifact in the EP
measurement band, for instance coupled 50/60 Hz
may not be seen in the EEG waveform because of
filtering.
●
Check that the electrode impedances are below
5 kOhm, and that the impedances of a same
channel are close to each other. If this does not
help, try to remove sources of noise.
