The effects of physical activity on sleep: a meta-analytic review (2015, methodology): “It is generally accepted that an increase in the amount of stage 1 sleep is a sign of sleep disruption, and thus a decrease in stage 1 sleep, as displayed in our results, is beneficial (Carskadon & Dement, 2000).”
Sleep deprivation: Impact on cognitive performance (2007, background): “The average sleep length is between 7 and 8.5 h per day (Kripke et al 2002; Carskadon and Dement 2005; Kronholm et al 2006).”
Sleeping on the motor engram: The multifaceted nature of sleep‐related motor memory consolidation (2017, positive): “Polysomnography (PSG), an electrophysiological technique measuring electrical activity of the brain [with electroencephalography (EEG)] as well as ocular and muscular activity [with electrooculography (EOG) and electromyography (EMG), respectively] is considered the gold standard for the objective a”
Learning‐dependent changes in sleep spindles and Stage 2 sleep (2006, background): “One of the most prominent features of Stage 2 sleep is the sleep spindle (Carskadon and Dement, 2000).”
Simultaneous EEG and fMRI of the alpha rhythm (2002, positive): “Because the alpha rhythm is present only when a subject is awake, the loss of this rhythm is used clinically to signify the first stages of sleep [5].”
