Theta frequency - Study guides, Class notes & Summaries

SSS/BETS (small sharp waves / benign epileptiform transients of sleep) Low voltage, short duration, diphasic spikes with a steep descending limb. Usually seen in drowsiness and light sleep. SREDA (subclinical rhythmic electrographic discharges of adults) Sharply contoured theta activity in the posterior head region. A normal variant in older adults during wakefullness. 14 and 6 positive spikes 1-2 seconds of sharply contoured discharges in the posterior head regions in light sle...
