Scholarcy highlights

  • We explore the brain processes that underlie human sleep and dreaming
  • We begin with a description of the push–pull of circadian rhythms that guide us toward sleep at night and toward wakefulness in the morning
  • Neuromodulators and hormones in the brain work in concert to provide changes in brain rhythms: we step through these processes as they trigger the onset of sleep in the evening, the shift between sleep stages throughout the night, and onset of wakefulness in the morning
  • Sleep is crucial for learning and memory: we describe how these processes are carried out in the brain, presenting recent research findings
  • There are many issues with natural sleep: we end the chapter with a discussion of insomnia, narcolepsy, and other sleep disorders
