Page 10 - EEG of Newborn and Infants

EEG of Premature (28-31 Weeks)

Continuity Discontinuous (tracé discontinu)
Interhemispheric synchrony Mostly asynchronous
Differentiation of waking and sleeping
Posterior basic alpha rhythm Undifferentiated
Slow activity (awake)
Temporal theta burst None
Occipital theta
Fast activity (awake) Very slow activity predominant
Low voltage
Tracé alternant Prominent (temporal sawtooth waves)
Spindles
Vertex waves and K complexes Decreasing
Positive occipital sharp transients
Slow and fast activity in sleep Frequent ripples or brushes around 16/sec (delta brushes)
REM sleep
Flat stretches, mainly asynchronous

None

None (but ripples present)

None

None

Much slow activity, more irregular, little fast activity

Undifferentiated
