EEG of Early Childhood (12-36 Months)

Continuity                              Continuous
Interhemispheric synchrony              No significant asynchrony
Differentiation of waking and sleeping  Good
Posterior basic alpha rhythm            Rising from 5-6/sec to 8/sec
Slow activity (awake)                   Considerable
Temporal theta burst                    None
Occipital theta                         None
Fast activity (awake)                   Mostly moderate
Low voltage                             Uncommon, usually abnormal
Tracé alternant                         None
Spindles                                In 2nd yr sharp and shifting, then symmetrical with vertex max
Vertex waves and K complexes            Large, becoming more pointed
Positive occipital sharp transients     Poorly defined
Slow and fast activity in sleep         Marked posterior maximum of slow activity
REM sleep                               Mostly slow, starting to become more desynchronized
