Season is related to the slow wave and sigma activity of infants and toddlers
2022, Sleep MedicineCitation Excerpt :In adults, SWA predominates in the beginning of sleep, when homeostatic sleep pressure is at its highest level, and diminishes towards the end of the night [5,10]. In infants, the temporal domination of SWA or deep sleep in the beginning of sleep emerges at one to four months of age [11–15]. In infants and young children, the SWA maxima locates in the posterior regions of the brain [16–19].
The maturation of cortical sleep rhythms and networks over early development
2014, Clinical NeurophysiologyDevelopmental profiles of infant EEG: Overlap with transient cortical circuits
2012, Clinical NeurophysiologyCitation Excerpt :These techniques revealed frequency dependent differences in power with sleep state (Curzi-Dascalova et al., 1988; Parmelee, 1969) and sleep position (Sahni et al., 2005), variance in power with clinical status (Scher, 1994), and differences between term and preterm infants (Scher et al., 1994a,b). Other investigators have characterized developmental changes in EEG during infancy, a notable study by Sterman et al. (1977) analyzed EEG data from birth to 24 weeks of age. They described a steady increase in low frequency power with postmenstrual age (PMA), while higher frequency power exhibited a “dip” from 40 to 44 weeks PMA.
Characteristics of sleep EEG power spectra in healthy infants in the first two years of life
2011, Clinical NeurophysiologyCitation Excerpt :To date, the description of sleep EEG power spectra of infants has been fragmented and visually qualitative. In addition, studies have been limited to small sample sizes (Jenni et al., 2003; Parmelee, 1969; Schulte and Bell, 1973), cross-sectional design (Samson-Dollfus et al., 1983; Schulte and Bell, 1973), duration less than the full first year of life (Jenni et al., 2003; Parmelee, 1969; Samson-Dollfus et al., 1983; Schechtman et al., 1994; Scher et al., 1994), analysis of specific sleep stages or specific bandwidths (Schechtman et al., 1994; Sterman et al., 1977), and provision of either graphical (Jenni et al., 2003; Schulte and Bell, 1973) or quantitative (Samson-Dollfus et al., 1983) description of sleep EEG power spectra. For example, the appearance of sleep spindles in infants corresponds with a noticeable peak in the QS/NREM N2 power spectra in the sigma (11–15 Hz) bandwidth (Jenni et al., 2003).
Ontogeny of EEG sleep from neonatal through infancy periods
2011, Handbook of Clinical NeurologyCitation Excerpt :A short list of these unique electrographic/polysomnographic behaviors include a shorter sleep cycle, prominent EEG delta rhythms in different regional locations, intra- and interhemispheric electrographic asynchrony, discrete neonatal waveform patterns (i.e., delta brush and theta burst patterns), a high percentage of periodic breathing, a greater number and heterogeneity of REMs, and unique motor patterns that reflect fetal postural reflexes which precede the expression of more sophisticated developmental movement patterns. Previous neonatal sleep studies initially applied automated techniques to assess functional brain maturation, using analyses that were based on assumptions of linearity, without consideration of time-dependent changes (Havlicek et al., 1975; Giaquinto et al, 1977; Sterman et al., 1977; Lombroso, 1979; Willekens et al., 1984; Connell et al., 1987; Bes et al., 1988; Eyre et al., 1988; Kuks et al., 1988). The preferred methodological approach has been fast Fourier transform analyses, studied initially with full-term neonates (Ktonas et al., 1995; Witte et al., 1997; Lehtonen et al., 1998; Eiselt et al., 2001; Field et al., 2002), followed by more recent reports in preterm infants (Sawaguchi et al., 1996; Eiselt et al., 1997; Myers et al., 1997; Holthausen et al., 2000; Schramm et al., 2000; Kuhle et al., 2001; Vanhatalo et al., 2002).
