Spindle‐like Fast Rhythms in the EEGs of Low‐birthweight Infants

Abstract: SUMMARY Quantitative analysis made on spindle‐like fast rhythms in the eegs of 39 low‐birthweight infants (28 pre‐term and 11 small‐for‐dates) resulted in four main findings. Spindle‐like fast rhythms occurred least frequently in the frontal area and most frequently in the occipital and/or central areas. They occurred more frequently at 31–32 weeks' post‐conceptional age than at 26–30 weeks, in all behavioural states. After 31 to 32 weeks they decreased with increasing age, to disappear completely around ter… Show more

“…During early prematurity they are more frequent during active than quiet sleep. From 29 to 34 weeks this changes and delta brushes are more frequent, and of higher amplitude, in quiet than active sleep (Goldie et al, 1971, Lombroso, 1979, Watanabe and Iwase, 1972, Scher, 2006, Koszer et al, 2006, Tharp et al, 1981, André et al, 2010). At later post-menstrual ages (34–42 weeks), although scattered delta brushes may be present during active sleep and wakefulness, quiet sleep is the only state in which they are prominent (Goldie et al, 1971, D’Allest and André, 2002, Niedermeyer, 2005, Statz et al, 1982).…”

“…A single study reports that the frequency of delta brushes during wakefulness is more than during quiet sleep but less than during active sleep until 33 weeks. From 34 to 42 weeks, delta brushes occur during wakefulness as often as during active sleep (Watanabe and Iwase, 1972). …”

“…The dominance of this pattern is illustrated by its many descriptions in the early literature (Khazipov and Luhmann, 2006), including “spindle-shaped bursts of fast waves” (Ellingson, 1958), “spindle-like fast rhythms” (Watanabe and Iwase, 2008), and “fast activity” (Goldie et al, 1971). These are now referred to delta brushes (8–28 Hz) in the clinical setting (André et al, 2010) and usually spindle bursts in the research setting.…”
