Questions and CORRECT Answers
Which waveform occurs at it's maximum amplitude in the central region of the brain? -
CORRECT ANSWER - Spindles and K complexes
Circadian rhythm control falls primarily under the control of what? - CORRECT ANSWER -
Suprachiasmatic Nucleus (SCN)
On a 24-hour cycle, the level of alertness is closely linked to what? - CORRECT ANSWER -
Body temperature
In what area of the brain do most seizures occur? - CORRECT ANSWER - Temporal
What structure is primarily involved in the control of wakefulness or alertness? - CORRECT
ANSWER - Reticular activating system (RAS)
What is the "gateway" structure between the body and the cerebral cortex? - CORRECT
ANSWER - Thalamus
Which neurochemical increases in REM sleep as well as wake? - CORRECT ANSWER - Ach
Sleep spindles result from the blocking of information between the____________ and the cortex
and result from deactivation of the _________. - CORRECT ANSWER - thalamus, RAS
Bright light therapy affects which anatomic structure? - CORRECT 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? - CORRECT ANSWER -
REM
, Pontogeniculate (PGO) waves are an indicator of which sleep stage? - CORRECT
ANSWER - REM
The EEG observed in wake and REM are both characterized by what? - CORRECT
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? - CORRECT ANSWER - Zeitgebers
Which come under the influence of circadian rhythm control? - CORRECT ANSWER - Body
temperature, hormone levels, and K+ levels
Destruction of the major endogenous circadian oscillator leads to: - CORRECT 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? - CORRECT 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: -
CORRECT 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: - CORRECT 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? -
CORRECT ANSWER - Importance of electrode channel in scoring, ease at which patient
falls asleep, and skill at fixing problem without waking patient
