2016 ACNS GUIDELINES RECOMMEDS A CMRR OF AT LEAST 90DB
FOR LOW FREQUENCY FILTERS THE CORRESPONDING TIME CONSTANTS FOR LFF CUTOFF
FREQUENCY OF 3 HZ WOULD BE 0.05 SEC
DIGITAL EEG MONTAGES ARE REFORMATTED BY USING SYSTEM REFERENCE
THE AMOUNT BY WHICH THE DIFFERENTIAL AMPLIFIER INCREASES THE MAGNITUDE OF THE
INPUT SIGNAL IS ITS SENSITIVITY
WHICH OF THE FOLLOWING PRICIPLES BEST APPLIES TO THE EEG AMPLIFIERS COMMON
MODE REJECTION
EEG AMPLIFIERS WORK ON THE PRINCIPLES OF DIFFERENTIATION AND AMPLIFICATION
THE SHARPNESS OF THE FREQUENCY RESPONSE CURVE IS DETERMINED BY THE FILTER
ROLLOFF
TIME CONSTANT OF 0.5 IS A HIGH PASS FILTER OF 0.3 HZ
,laplacian montage is.. source reference derivation
FOURTEEN AND SIX HZ POSITIVE SPIKES ARE BEST RECORDED WITH THE CONTRALATERAL
EAR REFERENCE

IS VEING MASKED BY MUSCLE ACTIVITY SENS OF 5, LF .3, HF 35
WHEN USING THE AVERAGE REFERENCE, IF A SPIKE AND WAVE FOCUS APPEARS AT C3, THE
ABNORMALITY WOULD BE BEST ENHANCED BY EXCLUDING C3 AND SURROUNDING
ELECTRODES FROM REFERENCE
WHAT IS THE BEST CHOICE TO CHOOSE FOR A REFERENCE ELECTRODE TO BE USED WHEN
RECORDING IN SUSPECTED TEMPORAL LOBE EPILEPSY CZ
A WAVEFORM OF 0.5 HZ CAN BE BEST ENHANCED WITH A LOW FREQUENCY FILTER OF WHAT
0.3 HZ
WHICH MONTAGE WOULD BE BEST TO LOCALIZE OCCIPITAL SPIKES BY PHASE REVERSAL
CIRCUMFERENTIAL BIPOLAR MONTAGE
TO ENHANCE THE BACKGROUND ALPHA AND BETA ASYMMETRY IN AN EEG RECORD SHOWING
MODERATELY HIGH VOLTAGE DELTA ACTIVITY, THE TECHNOLOGIST SHOULD USE A
SHORTER TIME CONSTANT AND INCREASED SENSITIVITY
WHICH OF THE FOLLOWING IS THE MOST APPROPRIATE INSTRUMENTATION SETTING CHANGE
THAT SHOULD BE MADE IN ORDER TO ENHANCE CORTICAL SLOWING CHANGE THE LFF
FROM 1 HZ TO .1 HZ

TOXIC EFFECTS OF WHICH OF THE FOLLOWING MEDICATION LITHIUM
ORDA IS COMMONLY SEEN IN CHILDREN WITH ABSENCE SEIZURES
WHICH OF THE FOLLOWING MEDICATIONS WOULD BE EXPECTED TO INCREASE BETA
FREQUENCY ACTIVITY XANAX
A 25 YEAR OLD FEMALE ADMITTED WITH NEW ONSET PSYCHOISIS WAS GIVEN 3 MG OF ATIVAN
PRIOR TO EEG RECORDING. HOW WOULD THIS MEDICATION AFFECT THE EEG INCREASED
BETA ACTIVITY
