“…Pioneering studies have shown that the EEG provides valuable prognostic information in preterm infants [32,[43][44][45][46][47][48][49][50] , and this has been confirmed by other more recent studies [25,[51][52][53][54][55][56][57] .…”

“…It is clear that both dysmature and disorganized patterns in the neonatal EEG are associated with adverse outcomes [32,49,51,52,55,65,67,70] . Some features of both patterns may also be present simultaneously over a number of time periods [32] , and dysmature features can also be seen in the acute stage abnormal EEG and intermingled with more disorganized patterns.…”

“…However, this may be a sign of abnormal maturation if consistently present during high-amplitude burst activity in infants ≥ 28 weeks' GA, during bursts of temporo-occipital delta activity in those between 30 and 34 weeks' GA, and if present during active sleep in infants aged 35-36 weeks [40, 84, 85] . As a result, asynchrony has been included as a feature of a dysmature neonatal EEG pattern by some authors [52] . There is some evidence to suggest that asynchrony may reflect an Color version available online alteration in subcortical signalling (of thalamic origin) and of progressive synaptogenesis in the corpus callosum, which are believed to be responsible for synchronization [10,85] ( Fig.…”

This review focuses on the role of electroencephalography (EEG) in monitoring abnormalities of preterm brain function. EEG features of the most common developmental brain injuries in preterm infants, including intraventricular haemorrhage, periventricular leukomalacia, and perinatal asphyxia, are described. We outline the most common EEG biomarkers associated with these injuries, namely seizures, positive rolandic sharp waves, EEG suppression/increased interburst intervals, mechanical delta brush activity, and other deformed EEG waveforms, asymmetries, and asynchronies. The increasing survival rate of preterm infants, in particular those that are very and extremely preterm, has led to a growing demand for a specific and shared characterization of the patterns related to adverse outcome in this unique population. This review includes abundant high-quality images of the EEG patterns seen in premature infants and will provide a valuable resource for everyone working in developmental neuroscience.

“…[40][41][42][43][44] The behavioral correlates of REM sleep are seen as early as 28-30 w CA when the EEG was still undifferentiated; recognizable EEG patterns of REM and NREM sleep first appear at 32-34 w CA. 32,33,45,46 Piaget 47 and Piers and Piaget 48 thought play was the major "work" of children, but for infants it is sleep. Newborn fullterm infants typically spend 16-18 h per day sleeping.…”

In March 2014, the American Academy of Sleep Medicine (AASM) Board of Directors requested the Scoring Manual Editorial Board develop rules, terminology, and technical specifications for scoring sleep/wake states in full-term infants from birth to 2 mo of age, cognizant of the 1971 Anders, Emde, and Parmelee Manual for Scoring Sleep in Newborns. On July 1, 2015, the AASM published rules for scoring sleep in infants, ages 0-2 mo. This evidence-based review summarizes the background information provided to the Scoring Manual Editorial Board to write these rules. The Anders Manual only provided criteria for coding physiological and behavioral state characteristics in polysomnograms (PSG) of infants, leaving specific sleep scoring criteria to the individual investigator. Other infant scoring criteria have been published, none widely accepted or used.The AASM Scoring Manual infant scoring criteria incorporate modern concepts, digital PSG recording techniques, practicalities, and compromises. Important tenets are: (1) sleep/wake should be scored in 30-sec epochs as either wakefulness (W), rapid eye movement, REM (R), nonrapid eye movement, NREM (N) and transitional (T) sleep; (2) an electroencephalographic (EEG) montage that permits adequate display of young infant EEG is: F3-M2, F4-M1, C3-M2, C4-M1, O1-M2, O2-M1; additionally, recording C3-Cz, Cz-C4 help detect early and asynchronous sleep spindles; (3) sleep onsets are more often R sleep until 2-3 mo postterm; (4) drowsiness is best characterized by visual observation (supplemented by later video review); (5) wide open eyes is the most crucial determinant of W; (6) regularity (or irregularity) of respiration is the single most useful PSG characteristic for scoring sleep stages at this age; (7)

“…Consequently, there is a need to identify high-risk newborns as early as possible so they can be provided with specific care. EEG is one of the most useful and non-invasive tools for predicting neurological outcome in preterm and term infants 6 8–14. However, previous reports have mainly focused on severe motor sequelae, and children were not usually followed past 1 or 2 years after birth 4 8 11.…”
