ABSTRACT
Despite evolving technologies, electroencephalography (EEG) remains a powerful tool for neurological diagnosis and prognosis in both preterm and term neonates. Neonatal EEG is different from children and adult’s EEG technically and also because it changes week by week as a result of brain maturation and growth. An EEG finding normal in a developmental stage may be abnormal in a different developmental stage owing to these rapid changes of brain growth. So it is important to know normal patterns of neonatal EEG in different conceptional weeks and behavioral states (sleep, awakeness). In this section, technical and qualitative features of normal neonatal EEG will be mentioned, normal graphoelements and maturational changes on the EEG background of neonates going through preterm to term age will be described.
Keywords: Infant, newborn; electroencephalography
