| Fragments of trace alternant may persist in quiet sleep up to __ weeks CA | 44 |
| In neonates, abnormalities are suggested if there is an asymmetry greater than __ : __ | 2, 1 |
| Bursts are defined a synchronous if they occur occur within ___ seconds of one another from left to right | 1.5 |

| Normal left to right burst synchrony in __ % in 31-32 week CA neonates | 70 |
| Normal left to right burst synchrony in __ % in > 37 week CA neonates | 100 |
| Voltage is considered abnormally low in full term > 43 week CA infants if it is less than __ - __ uV while awake or less than __ - __ uV in quiet sleep | 5, 10, 10, 25 |
| Normal neonatal EEGs become __ (more/less) continuous with stimulation | more |
| Normal neonatal EEGs become __ (higher/lower) in ampliutde with stimulation | lower |
| 3 EEG patterns that are normal in 24-29 week CA neonates | delta brush, monorhythmic occipital delta, rhythmic temporal and occipital delta |
| There is __ (more / less) monorhythmic occipital delta at 30 - 34 weeks than there is at 24-29 weeks | less |
| There is __ (more / less) rhythmic temporal theta at 30 - 34 weeks than there is at 24-29 weeks | more |
| The EEG at 24-29 weeks CA is: (A) Entirely continuous (B) Somewhat continuous during wakefulness & active sleep (C) Somewhat continuous during all stages (D) Entirely discontinuous | D |
| The EEG at 30-34 weeks CA is: (A) Entirely continuous (B) Somewhat continuous during wakefulness & active sleep (C) Somewhat continuous during all stages (D) Entirely discontinuous | B |
| The EEG at 30 - 34 weeks is totally discontinuous during ___ (stage(s)), and more continuous during ____ (stage(s)) | quiet sleep, active sleep, wakefulness |
| The name for the completely continuous pattern seen during wakefulness and active sleep in patients beyond age 35 weeks CA | Activite moyenne |
| Activite moyenne is seen beyond age __ weeks CA | 35 |
| The activity in neonates at 35 - 36 weeks during quiet sleep is __ (continuous / discontinuous) | discontinuous |
| The name for the pattern associated with quiet sleep in 35-36 week CA neonates | trace alternant |
| Beginning at week __ CA, the discontinuous activite moyenne is admixed with continuous slow wave sleep | 37 |
| The pattern seen in 37 - 40 week CA neonates during wakefulness and active sleep | activite moyenne |
| Continuous slow wave sleep should replace trace alternant by __ weeks CA | 44 |
| Sleep spindles appear by __ - __ weeks CA | 45, 46 |
| AT 30 - 34 weeks, this is the state in which the most delta brushes are seen | active sleep |
| Monorhythmic occipital delta activity peaks between __ and __ weeks and disappears by __ weeks | 31, 33, 35 |
| Rhythmic occipital theta activity peaks at age __ weeks and disappears by __ weeks | 30,33 |
| Rhythmic temporal theta activity peaks between __ and __ weeks | 31, 33 |
| Delta brushes are more prominent in active sleep up to age __ weeks, and more prominent in quiet sleep after age __ weeks CA | 33, 34 |
| This pattern refers to paroxysmal brief bursts of frontally dominant semirhythmic delta activity that may be sharply contoured | anterior dysrhythmia |
| Anterior dysrhythmia is more common in: (A) Wakefulness (B) Active sleep (C) Quiet sleep (D) All sleep stages | D |
| Marked, persistent asymmetry in the __, __ or __ of anterior dysrhythmia may indicate abnormalities | amplitude, morphology, number |
| This phrase is used to describe the reduction of complex faster polyfrequency background EEG patterns; it does not necessarily imply low voltage, although many records will be low voltage (and discontinuous and nonreactive.) | depressed and undifferentiated |
| High amplitude (>150 uV) broad biphasic frontal sharp waves (negative-positive) maximal bilaterally, synchronously | encoches frontales |
| Encoches frontales first appears at week __ CA | 34 |
| Encoches frontales usually disappears about __ weeks after birth | 4 |
| The best state(s) to evaluate sharp waves | active sleep, wakefulness |
