Some EEG stuff
EEG activity is usually observed in people relaxing.
What pattern are alpha waves?
EEG providing supportive evidence of brain death.
What is ECI?
A good method to remove eye blinks from EEG.
What is ICA?
A disease cause by prion infection.
What is Creutzfeldt-Jakob Disease?
A brain disorder that is treated with benzodiazepines.
What is epilepsy/seizure?
What is sweat sway?
An early ERP component recorded on the occipital area that can be positive or negative.
What is C1?
The system used to position the electrodes on the subject's scalp.
What is 10-20 system?
100 to 200ms.
What is the duration of a proper ERP baseline?
Positive or negative.
What is the polarity of an ERP component?
What are muscle artifacts?
The fact to reject a null hypothesis when this one is true.
What is a type 1 error?
60Hz.
What is the frequency of the electrical system in the United States?
Substracting the ERP components in one condition to the one in another condition.
What is a difference wave?
Removes the frequencies of the EEG signal that are under 0.1Hz.
What does a high pass filter/low filter do?
A technique used to trigger seizures in patients.
What are activation methods?
The removal of trials presenting artifacts in the EEG.
What is artifact rejection?
A software that is used to localize dipoles corresponding to the ERP components.
What is BESA/Loreta?
The signal before the presentation of a stimuli that is not on average equal to 0.
A poor baseline.
A statistical tool used to correct the p values of tests involving multiple comparisons.
What is Greenhouse-Geisser/Huynh-Feldt epsilon?
The impossibility to localize the generators of ERPS.
What is the inverse problem?
The sampling rate of and EEG system must be equal to twice the maximum value of highest frequency we want to study.

The origins of most ERPs.
what are postsynaptic potentials.
There is no substitute to clean data.
