There are two types of sleep: rapid eye movement (REM) sleep and non-REM (NREM) sleep. Changes in brain activity that take place are measured using an electroencephalogram (EEG). In older adults, fluency or experience with a task can reduce brain activity levels – in one sense this is greater processing efficiency. But the brain also declines the more we stop using it and with age.

    reductions in activity across sleep stages as VLPO neurons show progressive activation. Therefore, activation of VLPO neurons induces inhibition of the wake-promoting neuronal cells associated with the ARAS. Interestingly, the brain stem wake-promoting cells feed back and inhibit the VLPO sleep-promoting neurons. Thus, a sleep process starting with activation of the VLPO region would inhibit Mechanisms behind sleep loss effects.
