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.

• The higher the
score the more mature the neonate's brain.
• The maximum
scores occurred at 35-36 weeks postconception (last menstrual period minus 2
weeks).
