QUESTIONS SET A+
✔✔damage to wernickes area may result in - ✔✔receptive, fluent aphasia
✔✔brocas area lies in the ... - ✔✔posterior part of the inferior frontal gyrus
✔✔the fissure that separates the temporal lobe from the frontal - ✔✔sylvian
✔✔rolandic gyrus is between what lobes - ✔✔frontal and parietal lobes
✔✔what can happen in the brain that would be an immediate threat to life - ✔✔epidural
hematoma
✔✔difference between ataxia and apraxia - ✔✔ataxia - loss of controlled and
coordinated voluntary muscle movements due to muscle weakness or injury to
cerebellum. you also will have a hard time talking because it will be hard to form words
with mouth muscles
apraxia- inability to carry out purposeful movements in the absence of motor or sensory
impairment (your brain knows what it wants to do but it cant carry out the movement)
✔✔the onset of sturge-weber disease is typically during - ✔✔infancy
✔✔which of the following measures the opposition to current flow when a known
voltage is applied - ✔✔impedance meter
✔✔extremely low voltage due to phase cancellation may be caused by - ✔✔salt bridge
✔✔a single attenuated channel of eeg may be the result of - ✔✔inter-electrode spacing
too close
, ✔✔which of the following extra electrodes might best demonstrate the eeg activity
associated with focal motor twitching of the right corner of the mouth - ✔✔c5
✔✔input impedance should be very high or very low? - ✔✔very high
✔✔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

✔✔laplacian montage is.. - ✔✔source reference derivation
✔✔fourteen and six hz positive spikes are best recorded with - ✔✔the contralateral ear
reference
✔✔which combination of settings will help enhance a low voltage slow wave that 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
