The Neuroscience of Sleep

Why do we sleep and why is it such an important part of our life? Every evening, our body goes into the state of reduced consciousness for a few hours and restores the resources and the energy spent the day before. While it has been established that the need for sleep is largely dictated by the brain, the roles of different stages of sleep remain largely unknown. We will take a deep dive into how different brain regions regulate our sleep, and how the coordinated effort of body systems produces different sleep patterns throughout life. We will also discuss the impact of sleep physiology on our daily function.

Schedule clarification: This is a four-week online course. It runs from Monday, November 8 to Friday, December 3. Each week, all week, you can study that week’s material, post and respond to discussion board topics, and engage in course activities. You will participate in Zoom Meetings sessions each Friday from 10:30 a.m.–12 p.m. Pacific Time.

Learning objectives

By the end of the course, you should be able to do the following:

  • Describe different neurotransmitter systems that regulate sleep and wakefulness
  • Relate the activity of different brain regions to different states of consciousness
  • Examine the impact of different lifestyles on sleep patterns

Learning methods

Your online learning will include the following methods:

  • Reading academic and non-academic articles
  • Participation in written discussions with other students
  • Participation in discussion in videoconference seminars

For Liberal Arts for 55+ Certificate students: you will write a reflective essay.

Schedule

Week 1: Neuroanatomy and neurochemistry of sleep

Sleep as a state is a result of an orchestrated effort of many brain regions and networks. The chemical signals sent from one region to another regulate which parts of the nervous system become more or less activated during sleep.

Week 2: Regulation of sleep and arousal: sleep stages

Apart from the general state of reduced consciousness, sleep can be broken down into four stages that alternate throughout the night. The switch between different stages of sleep is regulated by the brain networks explored in the previous week.

Week 3: Circadian rhythms: how sleep structures life

The way the body physiology adapts to light and dark cycles is governed by the circadian rhythms. Apart from inducing sleep and wakefulness, circadian rhythms influence other body functions, such as body temperature, hormone release and hunger.

Week 4: Sleep need and impairment/advances in sleep research

Most people underestimate the impact of insufficient sleep on their daily life and general health. Recent advances in sleep science have improved our understanding of the role of sleep and how a lack of sleep impacts body physiology and society in general.
