RPSGT Exam with Accurate Solutions
Which waveform occurs at it's maximum amplitude in the central region of the brain? -
ANS-Spindles and K complexes
Circadian rhythm control falls primarily under the control of what? - ANS-
Suprachiasmatic Nucleus (SCN)
On a 24-hour cycle, the level of alertness is closely linked to what? - ANS-Body
temperature
In what area of the brain do most seizures occur? - ANS-Temporal
What structure is primarily involved in the control of wakefulness or alertness? - ANS-
Reticular activating system (RAS)
What is the "gateway" structure between the body and the cerebral cortex? - ANS-
Thalamus
Which neurochemical increases in REM sleep as well as wake? - ANS-Ach
Sleep spindles result from the blocking of information between the____________ and
the cortex and result from deactivation of the _________. - ANS-thalamus, RAS
Bright light therapy affects which anatomic structure? - ANS-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? - ANS-
REM
Pontogeniculate (PGO) waves are an indicator of which sleep stage? - ANS-REM
A K complex is observed at the end of epoch 60. Low voltage mixed frequency EEG
with increased EMG is observed up through epoch 64. Another k complex is observed
at the start of epoch 65. How would you score epoch 61-64? - ANS-N2
According to AASM Scoring criteria what is true in regards to scoring wake for epochs
with major body movements? - ANS-Alpha is present leading into major body
movements
