Dynamic EEG parameters in the frontal and parietal lobes in early sleep. The velocity in the frontal lobe was greater than in the parietal lobe in early (a p < 0.00001) and late sleep (b p = 0.0002). Moreover, in early sleep, velocity increased in the frontal lobe until day 30 and decreased over the following days. The same trend exists in late sleep, except at day 38. According to 2-way ANOVA, maturation dependency is significant (p = 0.0061). Regional differences in trajectories from Wake to NREM exist in early sleep (b p = 0.0011), while trajectory relates to age only in late sleep (c p = 0.0087). Micro-arousals from NREM to wake vigilance states show age-dependent alteration during early (e p = 0.0061) and late sleep (f p = 0.0351). During early sleep, the number of micro-arousals in the parietal lobe is significantly greater than in the frontal lobe (p = 0.0015)
