Ontogenesis of sleep spindles was studied on overnight longitudinal recordings in 12 full-term infants at 1.5-3-4.5 and 6 months of life. Six parameters (density, duration, frequency, amplitude, asymmetry and asynchrony) were analyzed during both slow wave sleep (SII and delta) and during 5 periods of the night. Results show a significant increase of most parameters between 1.5 and 3 months of age. All spindle patterns developed quite rapidly during the first 3 months of infancy, possibly reflecting developmental changes in thalamo-cortical structures and maturation of the physiological system that produces spindles. The density of 12-14 Hz spindle frequency was higher in stage II when compared to stage delta, as in adults. Our data confirm previous reports on spindle ontogenesis and give a more complete aspect of this ontogenesis in relation to sleep development. Three months of age appeared to be a turning point in maturational processes and might reflect changes in central nervous system activity and behavior which take place during that period. Sleep spindle evolution seems to be an accurate reflection of the slow wave sleep (SWS) development, and our results are discussed in terms of the developmental aspect of SWS production and characterization of sleep stages in young infants. Concordance between quantitative aspects and nocturnal organization leads us to consider that the individualization of slow wave sleep (SWS) in infants occurs from 4.5 months of life.
