Neonatal EEG 1

QuestionAnswer
The electrodes that are typically left off for neonatal EEG Fp1/Fp2, F7/F8, T5/T6, F3/F4, P3/P4
Special electrodes that are included for neonatal EEG Fp3, Fp4, Fz, Cz, Pz
__ and __ are electrodes used in neonates between Fp1 and Fp3, and Fp2/F4 Fp3, Fp4
Fp3 is an electrode situated between standard 10-20 electrodes __ and __ Fp1, F3
Additional channels often used in neonatal EEG respiratory, EOG, EKG, EMG
Electrode impedence should be less than __ Ohms (__ kOhms) for neonatal EEG 5000, 5
Suck artifact is often most common in the __ electrodes temporal
Frontal cerebral activity should be __ (in/out) of phase in the eye channels; eye movements should be __ (in/out) of phase in the eye channels in, out
EKG artifact in neonates is most common in the __ electrodes temporal
Pulse artifact is most prominent in the __ electrodes Cz
Cardiac recoil most often results in artifact in the __ electrodes occipital
The earliest EGA at which behavior can be used to determine sleep vs. wakefulness is ~ __ weeks 24
In __ sleep in an infant, the infant's eyes are closed but there are a variety of large and small body movements; brief apneas are relatively common active
Newborn infants __ (always/ frequently/rarely/never) enter active sleep from wakefulness frequently
In infants in __ sleep, the eyes are closed and there are few movements; apnea is uncommon quiet
Apnea is more common during __ sleep active
An infant's EEG is most vulnerable to adverse neurologic events during __ sleep quiet
Much of the EEG is spent in __ sleep, which is neither active nor quiet indeterminate
The earliest vestiges of EEG activity appear at week __ EGA 8
The discontinuity of a neonatal EEG is quantified by the __ __ interburst interval
Neonatal EEGs that display a relatively steady amplitude are termed __ continuous
Neonatal EEGs that alternate between high amplitude "on" periods and low amplitude "off" periods are termed __ (not burst-suppression) discontinuous
The median IBI at 24 weeks is __ seconds 10
Prolonged IBIs have been associated with __ and __ hyperammonemia (in citrullinemia), hypoxia
The two components of symmetry assessed in neonatal EEGs amplitude, waveform composition
__ in neonates is defined as bursts of morphological similar EEG activity in homologous head regions separated by more than 1.5 to 2.0 seconds in time asynchrony
__ is a phenomenon whereby bursts of activity arise in the two hemispheres at the same time in neonates; it is seen before EGA __ weeks hypersynchrony, 30
About __% of bursts of activity during quiet sleep are synchronous at age 31-32 week EGA; __%35-36% and __% after 37 weeks 70, 85, 100
For a 24-29 week EGA, the EEG __ (does/does not appear distinctly different during sleep and wakefulness does not
For the EEG of a 24-29 week EGA infant, the EEG __ (does/does not) demonstrate reactivity does not
The EEG of an otherwise healthy 24-29 week EGA neonate shows __ (no/some/constant) continuity no
The bursts of a 24 - 29 week EGA neonate show __ (asynchrony/hypersynchrony/synchrony) in 100% of patients hypersynchrony
The typical interburst interval in 24-29 week EGA neonates 6-12 seconds
The typical interburst amplitude in 24 - 29 week EGA neonates < 2 microvolts
The bursts of activity for a 24-29 week EGA neonate show most activity in these regions temporal occiptial
The EEG for a neonate at 30-34 EGA __ (does/down not) appear the same in active sleep, quiet sleep and wakefulness does not
In a 30-34 week EGA neonate, the EEG appears more discontinuous during this state quiet sleep
Discontinuous patterns of quiet sleep (as seen in 30-36 week EGA neonates) are known as this trace discontinu
The EEG of a 30-34 EGA neonate __ (does/does not) demonstrate reactivity does
Delta brush in neonates aged 30-34 EGA is seen more commonly in this state of sleep active sleep
Bursts are synchronized in ~ __-__% of EGA 30-34 week neonates 70-80
The interburst interval is ~ __-__ seconds in EGA 30-34 week neonates 5, 8
The amplitude of the interburst interval is __ in EGA 30-34 neonates < 25 microvolts
Bursts in EGA 30-34 week neonates have more prominent rhythmic activity in the __ regions temporal, occipital
