Global HI resulted in prolonged profound suppression of preterm brain function. (A) Observed mean IBI length (log scale) per 24 hours of two animals, one sham and one HI, superimposed on observed mean IBI length per 30 minutes; (B) Values predicted by the mixed linear model are superimposed on observed IBI length per 24 hours of all animals. IBI = interburst interval length, log = natural logarithm, s = seconds, UCO = umbilical cord occlusion, 30’ = 30 minutes, 24h = 24 hours, d = day.
