Page 26 - EEG of Newborn and Infants
P. 26
EEG of Full-term Newborn (36-41 Weeks)
Continuity Continuous except for tracé alternant in NREM (quiet) sleep
Interhemispheric synchrony Minor asynchronies still present
Differentiation of waking and sleeping Good
Posterior basic alpha rhythm None
Slow activity (awake) Slow (delta) mostly of moderate voltage
Temporal theta burst Disappearing or absent
Occipital theta Absent
Fast activity (awake) Decreasing ripples, sparse fast activity
Low voltage Very low voltage records due to serious cerebral pathology
Tracé alternant Present in NREM (quite) sleep
Spindles None (but scanty ripples)
Vertex waves and K complexes None
Positive occipital sharp transients None
Slow and fast activity in sleep Much delta and theta activity, continuous in REM sleep
REM sleep Continuous slow activity
