  • Circadian rhythm

    Regulates the sleep cycle
  • Suprachiasmatic nucleus (SCN)

    Part of the hypothalamus that drives the sleep cycle
  • Sleep-promoting nuclei

    • GABAergic nuclei in the brainstem
    • Lateral hypothalamus
    • Preoptic area
  • PPRF (paramedian pontine reticular formation/conjugate gaze center)

    Responsible for the extraocular movements that occur during REM sleep
    • Hypothalamus: controls onset of sleep ​
    • Hippocampus: memory region active during dreaming ​
    • Amygdala: emotion center active during dreaming ​
    • Thalamus: prevents sensory signals from reaching the cortex ​
    • Reticular formation: regulates the transition between sleep and wakefulness ​
    • Pons: helps initiate REM sleep. The extraocular movements that occur during REM are due to the activity of PPRF (paramedian pontine reticular formation/conjugate gaze center; horizontal gaze).​
