Abstract:Sleep spindles are thalamocortical oscillations that contribute to sleep maintenance and sleep‐related brain plasticity. The current study is an explorative study of the circadian dynamics of sleep spindles in relation to a polygenic score (PGS) for circadian preference towards morningness. The participants represent the 17‐year follow‐up of a birth cohort having both genome‐wide data and an ambulatory sleep electroencephalography measurement available (
N = 154, Mean age = 16.9, SD = 0.1 years, 57% girls). Ba… Show more
“…This stage is characterized by transient sleep spindles; EEG activity of 12-14 Hz which lasts a minimum of 0.5 seconds; and K complexes, EEG waves lasting about 0.5 seconds with a well-delineated negative deflection immediately followed by a positive one, creating a tracing resembling the letter K 3. High spindle frequency is correlated with sleep maintenance and brain plasticity and negatively correlated with mental health 4,5…”
Sleep can impact health and performance. With increased knowledge about sleep hygiene and sleep disorders, nurses can teach patients practical behaviors and strategies to promote healthy sleep habits and assist their journey to healing and recovery.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
