microvolts/mm
-LF = 5 Hz
-HF = 70 Hz
which of the following is the most appropriate
instrumentation setting change that should be made in
order to enhance cortical slowing? - Answer-Change the
LFF from 1 Hz to .1 Hz
Fourteen and six Hz positive spikes are best recorded
with - Answer-the contralateral ear reference
,The best reference electrode in an awake patient with
excessive temporal myogenic activity would be - Answer-
Cz
A slow wave focus is best seen with - Answer-LF 0.3 Hz,
paper speed 15 mm/sec
Laplacian montage - Answer-source reference derivation
EEG amplifiers work on the principle(s) of - Answer-
differentiation and amplification
Doubling the inter-electrode distances will have what
effect on the waveforms? - Answer-increase amplitude
term used to describe the. way a signal is sampled at
intervals and assigned a numeric value - Answer-
sampling rate
Digital EEG montages are reformatted by using - Answer-
system reference
,Input impedance should be - Answer-very high
Low sampling rate may cause fast frequencies to appear
slower: - Answer-aliasing
2016 ACNS guidelines recommends a CMRR of at least: -
Answer-90 dB

demonstrate the EEG activity associated with focal motor
twitching of the right corner of the mouth? - Answer-C5
sphenoidal electrodes are used to record activity from
the - Answer-anterior temporal lobes
, what additional electrodes could be placed to help
decipher between artifact and cortical activity - Answer-
EOG electrodes

age patient who repeatedly alerts from sleep during the
EEG? - Answer-Respiration
brain abscess - Answer-focal polymorphic delta activity
Cortical EEG recordings can be obscured in patients who
are tense and anxious due to - Answer-myogenic artifact
