Fig. 1: Examples the EEG variables studied in the visual and spectral analysis in an SGA term infant.

a and b Discontinuous EEG tracings showing interhemispheric asynchrony and asymmetry, respectively, with transient rolandic sharp waves (vertical arrow), interburst interval (two-headed arrow) and delta brushes in the bursts (Inclined arrows). c Interhemispheric asymmetry of the bursts on the EEG background with tracé alternant and transient temporal sharp waves (vertical arrow). d Graphs and topographic maps of absolute power spectrum in the δ, θ and α frequency bands; the values in the color scale represent absolute power spectrum in µV2.
