Explore the stages of a good night's sleep and the research linking sleep to memory.

One Family, Different Clocks

The brain is the home of the body’s internal clock. Genetics can alter this clock, as the 2012 second place Brain Awareness Video Contest winner explains.

Sleep Disorders

Source: Society for Neuroscience
Sleep disorders keep millions up at night, but their causes are diffuse and their symptoms can be very different from one another.

Sleep: An Overview

Source: Society for Neuroscience
Sleep is crucial for concentration, memory, coordination, and even emotional health. Research holds promise for devising new treatments to allow millions of people to get a good night’s sleep.

Brain Activity During Sleep

Source: Society for Neuroscience
Although sleep appears to be a passive and restful time, it actually involves a highly active and well-scripted interplay of brain circuits, resulting in sleep’s various stages.

The Sleep-Wakefulness Cycle

Source: Society for Neuroscience
Why do we get sleepy? There are two main determining factors: the circadian system (time of day or night) and how long we have been awake.

How Is Sleep Regulated?

Source: Society for Neuroscience
What is the difference between sleep and wakefulness? Much of it depends on which brain systems are activated.

Yawning

Yawning is both familiar to everyone and totally mysterious, as scientists continue to puzzle over its possible functions.

The Different Kinds of Sleep

Source: CIHR – Institute of Neurosciences, Mental Health and Addiction
Each of us spends about one-third of our life asleep. By the time you’re 75, you will have spent 25 years sleeping. Suppressing sleep for an extended period has dramatic effects on an organism’s physiological equilibrium.

Sleep Disorders

People are too quick to label others as lazy if they accord a lot of importance to their sleep. But if there’s one thing for which we should show more respect, it’s our need for a good night’s sleep.

The Sleep Cycles in a Night

Source: CIHR – Institute of Neurosciences, Mental Health and Addiction

There are two main types of sleep, REM sleep and non-REM sleep, and non-REM sleep in turn is divided into four stages. But how are these various kinds of sleep distributed over the course of a night? In what order do they occur? Are they repeated several times?

The National Institutes of Health (NIH) Curriculum Supplement Series provides interactive teaching units that combine cutting-edge science research discoveries from the NIH with state-of-the-art instructional materials. Each supplement is a teacher's guide to two weeks of lessons on science and human health.

Narcolepsy

Source: Society for Neuroscience
Scientists have identified some of narcolepsy’s underlying genetic and neurobiological causes — discoveries that reveal biological mechanisms of sleep disorders and potential treatments.

Mysteries and Importance of Anesthesia

Source: The National Institute of Mental Health
How the brain reacts to anesthesia is a neuroscientific phenomenon that includes a dash of mystery. But the study of anesthesia could lead to treatment of sleep issues frequently associated with many mental disorders.
