Burdjalov et al developed a score based on the cerebral function monitoring (CFM) of a neonate. This can help determine the neonate's CNS status. The authors are from the State University of New York at Stony Brook.
The CFM unit consists of a compressed, single-channel amplitude integrated EEG based on readings from 2 biparietal electrodes.
Parameters:
(1) bandwidth span in µV
(2) amplitude of lower border in µV
(3) continuity
(4) cycling

total score =
= SUM(points for all 4 scored parameters)
Interpretation:
• minimum score: 0
• maximum score: 12
• The higher the score the more mature the neonate's brain.
• The maximum scores occurred at 35-36 weeks post-conception (last menstrual period minus 2 weeks).
