Preserved wake-dependent cortical excitability dynamics predict cognitive fitness beyond age-related brain alterations
[article]

pre-print
Age-related cognitive decline is rooted in alterations in brain integrity as well as in sleep-wake regulation. Here, we investigated whether preserved sleep-wake regulation of cortical function during wakefulness could represent a positive factor for cognitive fitness in aging, independently of early age-related alterations in brain structure associated with Alzheimer's disease neuropathology. We quantified slow waves generation during sleep and cortical excitability dynamics during prolonged
