Detailed explanation-1: -Sleep spindles are one example of such a mechanism. Sleep spindles are bursts of coherent brain activity visible on the EEG, which are most evident during stage 2 sleep. They consist of brief 11-to 16-Hz waves lasting 0.5–1.5 s.
Detailed explanation-2: -Sleep spindles are an electroencephalographic (EEG) hallmark of non-rapid eye movement (NREM) sleep and are believed to mediate many sleep-related functions, from memory consolidation to cortical development.
Detailed explanation-3: -A sleep spindle is a rapid burst of higher frequency brain waves that may be important for learning and memory (Fogel & Smith, 2011; Poe, Walsh, & Bjorness, 2010). In addition, the appearance of K-complexes is often associated with stage 2 sleep.
Detailed explanation-4: -Sleep spindles are characteristic electroencephalogram (EEG) signatures of stage 2 non-rapid eye movement sleep.
Detailed explanation-5: -Distinctive bursts of sleeping-brain activity, known as sleep spindles, have long been generally associated with strengthening recently formed memories. But new research has managed to link such surges to specific acts of learning while awake.
