Brief Summary

Sleep is ubiquitous in animals and humans, and disruptions are of high clinical importance. Still, the neural basis of sleep perception is insufficiently understood, which limits the development of new treatments. The current project is designed to further contribute to the understanding of the neural basis of sleep perception and to the development of innovative treatments for disrupted sleep (insomnia).

  • Current or past substance abuse or dependency
  • Smoking \> 5 cigarettes per day
  • Excessive caffeine consumption (\> 500 mg or 5 cups coffee per day)
