Pattern of EEG from<28-34 weeks
Trace discontinu
Discontinuous with high and low bursts
IBI >5 but <25 uV

10s
6s
Order that states become continuous
Active>awake> quiet by 38-40 weeks
What is Trace alternan, age
Quiet sleep pattern 36-38 wks
Now low burst is 25-50uV
3-10 s high amp burst
3-5 low
Which state is first and last to become synchronous?
REM then awake and quiet sleep last,
Less than 27 weeks everything is synchronous
What are delta brushes? What age and location?
Marker of prematurity
0.3-1.5Hz delta with overriding fast 18-22 Hz activity
25-38 weeks
Gone by 44 wks
Start centrally then move to temporal then occiptial
Age of temporal theta and temporal
Alpha bursts
Gone by

What are frontal sharps
Blunt sharp waves 32-46 weeks, negative then longer positive phase
Often central and bitemporal
Synchronous and symmetric
Positive sharp mean what?
Marker of parenchyma or deep white matter injury
