The electroencephalogram (EEG) is an essential tool to monitor the acute and long-term effects of insults on brain function, especially in the first years of life. The functional information coming from EEG is also a valuable guide to diagnose and to plan the treatment of seizure disorders and to exclude the presence of an organic brain disease. The interpretation of pediatric EEG, particularly in neonates and infants deserves proper knowledge about the maturation of EEG. The neuro-physiological maturation of fetal human brain occurs in close relation with the anatomical and functional development of cortical and subcortical structures. In the early years of life, particularly between 28 and 40 weeks of age, the human brain demonstrates an enormous change in term of gross and microstructural anatomical development, organization and the synaptogenesis of cerebrum. EEG perfectly reflects this maturational process. This chapter aims to outline the developmental aspects of EEG from prematurity to adulthood
