'Posterior temporal fast' EEG activity in childhood.
Posterior temporal fast (PTF) EEG activity has been studied in 352 children (706 EEGs) from 1967 to 1982. During this period a total of 42,600 EEGs have been recorded. The rhythmic activity detected as PTF was of 18-30 c/sec but usually at 20-26 c/sec, varying in amplitude between 50 and 300 microV. It appears in runs lasting seconds, often in some sort of irregular spindling. Its frequency but not its amplitude tends to be fixed in each child. This EEG activity (not previously described) appears, or disappears, in response to a variety of environmental stimuli. PTF was seen in over 1% of children between 1 and 3 years of age becoming rare in older children.
