Sleep spindles<\/strong> are bursts of oscillatory brain activity visible on an EEG<\/strong> that occur mainly during stage 2 sleep. Sleep spindles are linked for example to sleep maintenance and strengthening of the memory traces during sleep<\/strong>.<\/p>\n The study explored the association between individual circadian preference and sleep spindle activity among 170 17-year-old participants, who underwent a sleep EEG monitoring at their home environment.<\/p>\n “We observed a significantly weaker spindle activity among the morning preference group compared to other groups<\/strong>. The spindle activity also decreased more towards the morning hours, explains the principal investigator,” Professor Anu-Katriina Pesonen. “This might be a potential facilitator underlying earlier circadian rhythm.”<\/p>\n The study published in\u00a0Scientific Reports\u00a0<\/em>shows for the first time a link between circadian preference and sleep maintaining sleep microstructures, indicated by sleep spindle activity.<\/p>\n<\/div>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":" From the University of Helsinki press release: A new study from the University of Helsinki, Finland, shows that individual circadian preference is associated with brain activity patterns during the night….
