Abstract
We compared frequency and power of neonatal EEG delta brush rapid oscillatory activity (ROA) using multiple band frequency analysis (MBFA) in three groups; pre-term (PT, post-conceptional age 33-35.6weeks, n=5); full-term (FT, 39.4-40.6weeks, n=5) and pre-term or full-term with phenobarbital exposure (PB, n=5). Mean number of delta brushes analyzed was 29.4 (range 26-47) in PT, 20.8 (14-33) in FT and 20 (7-37) in PB. Mean frequency±standard deviation (s.d.) was 16.9±2.1Hz (range 15-20Hz) in PT, 17.3±1.9Hz (15-20Hz) in FT and 16.1±1.6Hz (14-19Hz) in PB. Mean power±s.d. was 22.9±6.2μV 2 (range 16-39μV 2) in PT, 11.9±4.1μV 2 (7-19μV 2) in FT and 17.1±6.2μV 2 (9-26μV 2) in PB. Power was significantly higher in PT than FT (p2) than FT′ (11.4±3.6μV 2) (p
