In mice, the brain’s main glial cell type exhibits distinctive patterns of activity across the sleep-wake cycle and influences the response to sleep deprivation.

Habits such as napping might influence how humans cope with extreme environments, such as those at a polar research facility in winter.

“Short sleeper” mice engineered to have the same sequence in the gene sleep less but show the same performance on memory tests as animals that sleep a normal amount.

Neurons can only efficiently fix genetic injuries when the animals are asleep.

Sleeping on a rhythmically swaying surface helps synchronize sleep oscillations in the human brain, a study finds.

People who have suffered traumatic brain injury had slower reaction times and more false starts after disrupted sleep than healthy controls, according to a study presented at the Society for Neuroscience meeting.

A protein in skeletal muscles helps mice recover from sleep deprivation.

Two studies identify a signaling pathway that contributes to the fish’s sleeplessness.

Brain-derived neurotrophic factor affects onset and duration of REM in the animals, but not other phases of sleep.
