WebBeta activity is defined as a frequency of 13–30 Hz and is present in the background of most subjects. If completely absent it may represent an abnormality depending on other features of the EEG. Maximal beta amplitude is usually in the frontocentral regions, but it may be widespread. It does not respond to eye opening, as does the PDR. WebBreach Rhythms. • Higher voltage/amplitude due to break in skull bone. • Sharp, rhythmic, high amplitude waves seen over craniotomy sites. • Will always be localized (seen only in 1 or 2 channels) Rhythmic Temporal Theta Bursts of Drowsiness/Psychomotor Variant. • Occurs during light sleep and or drowsiness.

Routine electroencephalogram (EEG), recorded during awake and natural sleep (stage 1), did not show any high voltage slow wave epileptiform discharge. A photic stimulation showed no significant findings, and hyperventilation was not performed because the patient was unable to follow instructions. novasource feeding
