ANSWER: Reticular activating system (RAS)
What is the "gateway" structure between the body and the cerebral cortex? -
ANSWER: Thalamus
Which neurochemical increases in REM sleep as well as wake? - ANSWER: Ach
Sleep spindles result from the blocking of information between the____________
and the cortex and result from deactivation of the _________. - ANSWER: thalamus,
RAS
Bright light therapy affects which anatomic structure? - ANSWER: SCN
A tonic-clonic seizure represents the mass firing or synchronization of large groups of
neurons. Which sleep stage would you LEAST expect to see seizure activity? -
ANSWER: REM
Pontogeniculate (PGO) waves are an indicator of which sleep stage? - ANSWER: REM
The EEG observed in wake and REM are both characterized by what? - ANSWER:
Asynchronous EEG, low voltage, and mixed frequency
What general term is used to describe cues which synchronize our internal clock to
the external environment? - ANSWER: Zeitgebers
Which come under the influence of circadian rhythm control? - ANSWER: Body
temperature, hormone levels, and K+ levels
, Destruction of the major endogenous circadian oscillator leads to: - ANSWER:
Arrhythmicity
The technician observes muscle artifact in a single EEG channel that shares a
common reference with other channels. What is the appropriate response? -
ANSWER: Re-reference the channel showing artifact by changing the input signal
derivation to a back-up exploring electrode
The preferred method of correcting undesirable artifacts during the recording
process is to: - ANSWER: Change the input signal derivations
If 60Hz artifact is observed in one of the channels during the bio-calibration process,
the appropriate action should be: - ANSWER: Find the problem source and correct it
before beginning the study
What factors come into play when deciding to enter the patient's room to correct
artifacts? - ANSWER: Importance of electrode channel in scoring, ease at which
patient falls asleep, and skill at fixing problem without waking patient
Double-referencing (A1+A2) may be useful for? - ANSWER: Reduce EKG artifact in
EEG and EOG channels
The chief way of excluding undesirable interfacing signals in polysomnograph is
accomplished by: - ANSWER: Passing input signal through differential amplifiers
Which conditions are most likely to cause electrode-popping artifact? - ANSWER:
Pressure against the electrode and poor ground connection
Which type of artifact presents as a high frequency artifact? - ANSWER: Muscle
If the size of the prepared electrode site is too large, what can occur? - ANSWER:
Signal contamination or bridging
What is not considered a physiologic artifact? - ANSWER: Popping
Which types of artifacts are physiological? - ANSWER: Muscle, respiratory, and cardio
ballistic
What is one of the contributing causes of EKG artifact in the arm or leg leads? -
ANSWER: Voltage differences resulting from increased electrode distances
What is the first step in differentiating high frequency artifact caused from muscle
vs. a poor electrode connection? - ANSWER: Impedance check
What is true regarding the scoring of an epoch containing major body movement? -
ANSWER: Alpha coming into the movement constitutes scoring epoch as wake, and
